Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m;
support was removed in 8.0
With the problem above, I'm trying to start the jboss server. I tried some steps and I could not find the right solution.
Please use the following setting to allocate the memory for the permanent location -Xms1024m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m -XX:-UseGCOverheadLimit
You can try to increase eclipse memory, you can do this in le eclipse.ini file (near eclipse executable file) or in the command line arguments :
-Xms256m
-Xmx16348m
It is JBoss (not Eclipse) that is crashing. So increasing Eclipse's memory is futile! (It might make things worse, in fact.)
The second thing to note is that you are running out of space in a native allocation request, so increasing the regular heap's size will not help. Options like the following will probably NOT help! (They might make things worse, in fact.)
-Xms1024m -Xmx1024m -XX:-UseGCOverheadLimit # USELESS
The third thing to note is that your JVM doesn't have a PermGen space, so fiddling with the PermGen size via
-XX:PermSize=512m -XX:MaxPermSize=512m # USELESS
is futile. (That is what Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0 is saying.)
So what is the real problem?
Well you are running a 64-bit JRE, so it is not an architectural problem. (On a 32-bit JRE, the JVM's address space has hard limits ...)
In fact, it is a problem outside of the JVM itself. Basically, the JVM has asked the OS for more memory, and the OS has said "Nope!". I can thing of two possible explanations:
There may be a per-process "ulimit" in place, that is restricting the process size. Your JVM has requested beyond that limit.
The OS may have run out of virtual address space or mappable virtual memory. The former is unlikely. The latter typically arises because your OS doesn't have enough RAM and/or swap space. This can also happen is you are running within a virtual machine that is ... less than generous endowed with memory resources.
Now it appears that this may be happening when the JVM is trying to grow the Java heap. But either way, the problem is not the size of the Java heap.
I've started seeing the following error using 32-bit (and 64 for that matter) Java 6 (on Windows 8 x64. This wasn't an issue until some Windows updates were installed.....) to call ant scripts
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
Anyone ever seen it before? I've done some digging around SO and other places and haven't come across anything that's solved this issue for
Edit 8/24
So far, here are the following things I have attempted to fix the issue, none of which have worked:
Setting _JAVA_OPTIONS in system environment variables, up to 3gb for the maximum heap size
Setting JVM_OPTS in cmd before invoking ant, again max heap size up to 3gb
Passing in -Xms and -Xmx arguments when making the actual java call, like so %JAVA_HOME%\bin\java -Xms512m -Xmx2048m org.apache.tools.ant.Main
Setting the ANT_OPTS variable before calling ant
Uninstalling Windows updates going back before these issues.
Does anyone have a solution that differs from the following? As the other attempts have not been working..
When you run on 32-bit windows (or in the 32-bit windows emulator) you have only about 1.2 GB - 1.5 GB of virtual memory available. This size depends on what else you might have running in that space as it doesn't always isolate programs from each other in terms of memory space (i.e. the memory space is limit and shared)
So after updating windows, it could have installed a new program which is run before Java, or updated an existing which is using more memory.
The simplest solution is to use a 64-bit JVM which doesn't have this problem. Or you have to reduce the maximum heap size.
I'm trying to build a GWT project, using Maven. When gwt-maven-plugin tries to compile the code, it throws an error:
[ERROR] Error: Could not create the Java Virtual Machine.
[INFO] Could not reserve enough space for object heap
I tried mvn -Dgwt.extraJvmArgs=-Xmx1280m clean install, it didn't help.
An obvious solution is usually to set MAVEN_OPTS system variable. So, I've added MAVEN_OPTS with value -XX:MaxPermSize=512m -Xmx1280m. If I run echo %MAVEN_OPTS%, I see -XX:MaxPermSize=512m -Xmx1280m.
Now, if I try to run mvn clean install, I get:
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
That's strange, because task manager says, that I have 5.9 Gb of available RAM. Why can this error be thrown? Why cannot it reserve the desired space? I'm using 32-bit JVM and Windows 8.
UPDATE: 64-bit JVM helped. I didn't think, that -XX:MaxPermSize=512m -Xmx1280m is too much for 32-bit JVM.
You need to pass the configuration to the gwt-maven-plugin via
mvn -Dgwt.extraJvmArgs=-Xmx1280m clean install
see also http://mojo.codehaus.org/gwt-maven-plugin/compile-mojo.html
You could also try to reduce the amount of memory:
Could not reserve enough space for object heap
This sounds like the JVM can't reserve the desired space. Try -Xmx1024m or -Xmx768m.
If this also doesn't work, you could try to use a 64 bit JVM to compile the code.
facing some problem with java virtual machine initialization. when i am using root account i can properly work with java. but when i am a user account it returns following errors
user#host# $JAVA_HOME/bin/java -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
It does not seems like a memory issue as the same command works with root account. Available memory (free -m) is more than 1200MB
Also i have tried increasing the JVM memory limits
Just be careful. You will get this message if you try to enter a command that doesn't exist, e.g.:
/usr/bin/java -v
I had this issue today, and for me the problem was that I had allocated too much memory:
-Xmx1024M -XX:MaxPermSize=1024m
Once I reduced the PermGen space, everything worked fine:
-Xmx1024M -XX:MaxPermSize=512m
I know that doesn't look like much of a difference, but my machine only has 4GB of RAM, and apparently that was the straw that broke the camel's back. The Java VM was failing immediately upon every action because it was failing to allocate the memory.
Set the JVM memory:
export _JAVA_OPTIONS=-Xmx512M
The problem got resolved when I edited the file /etc/bashrc with same contents as in /etc/profiles and in /etc/profiles.d/limits.sh and did a re-login.
Make sure the physical available memory is more then VM defined min/max memory.
I am getting the following exception repeatedly each time I try to run the program.
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
I tried to increase my virtual memory (page size) and RAM size, but to no avail.
How can I eliminate this error?
Run the JVM with -XX:MaxHeapSize=512m (or any big number as you need) (or -Xmx512m for short)
This can also be caused by setting something too large on a 32-bit HotSpot vm, for example:
-Xms1536m -Xmx1536m
where this might/would work:
-Xms1336m -Xmx1336m
here is how to fix it:
Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System
Variables->New: Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M
Variable name: Path
Variable value: %PATH%;C:\Program Files\Java\jre6\bin;F:\JDK\bin;
Change this to your appropriate path.
I ran into this when using javac, and it doesn't seem to pick up on the command line options,
-bash-3.2$ javac -Xmx256M HelloWorldApp.java
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
so the solution here it so set _JAVA_OPTIONS
-bash-3.2$ export _JAVA_OPTIONS="-Xmx256M"
-bash-3.2$ javac HelloWorldApp.java
Picked up _JAVA_OPTIONS: -Xmx256M
And this compiles fine.
This happens to me on machines with a lot of RAM, but with lower memory ulimits. Java decides to allocate a big heap because it detects the ram in the machine, but it's not allowed to allocate it because of ulimits.
32-bit Java requires contiguous free space in memory to run. If you specify a large heap size, there may not be so much contiguous free space in memory even if you have much more free space available than necessary.
Installing a 64-bit version of Java helps in these cases, the contiguous memory requirements only applies to 32-bit Java.
Combined with -Xmx512M use -d64 to make sure you're running 64-bit VM. On a 64-bit machine I thought for sure I was running 64-bit virtual machine, but no. After installing 64-bit Java the -d64 option works and -Xmx allows much larger memory sizes.
java -d64 -Xmx512M mypackage.Test
Open gradle.properties file in android folder.
Replace this line:
org.gradle.jvmargs=-Xmx1536M
with:
org.gradle.jvmargs=-Xmx512m
Explanation:
Max limit from Gradle document:
If the requested build environment does not specify a maximum heap size, the Daemon will use up to 512MB of heap.
I got the same error and resolved this by configuring it in the run.conf.bat
Run the JVM with the configuring run.conf.bat in Jboss5x
If free memory is not available AS you are passing in the statement then please make changes in run.conf.bat
set "JAVA_OPTS=-Xms512m -Xmx512m -XX:MaxPermSize=256m"
I had similar issues. I had installed 32 bit version of Java on a 64 bit machine.
By uninstalling that version and installing 64 bit version of Java. I was able to resolve the issue.
I know there are a lot of answers here already, but none of them helped me. In the end I opened the file /etc/elasticsearch/jvm.options and changed:
-Xms2G
-Xmx2G
to
-Xms256M
-Xmx256M
That solved it for me. Hopefully this helps someone else here.
Suppose your class is called Test in package mypackage. Run your code like this:
java -Xmx1024m mypackage.Test
This will reserve 1024 MB of heap space for your code. If you want 512 MB, you can use:
java -Xmx512m mypackage.Test
Use little m in 1024m, 512m, etc
Sometimes, this error indicates that physical memory and swap on the server actually are fully utilized!
I was seeing this problem recently on a server running RedHat Enterprise Linux 5.7 with 48 GB of RAM. I found that even just running
java -version
caused the same error, which established that the problem was not specific to my application.
Running
cat /proc/meminfo
reported that MemFree and SwapFree were both well under 1% of the MemTotal and SwapTotal values, respectively:
MemTotal: 49300620 kB
MemFree: 146376 kB
...
SwapTotal: 4192956 kB
SwapFree: 1364 kB
Stopping a few other running applications on the machine brought the free memory figures up somewhat:
MemTotal: 49300620 kB
MemFree: 2908664 kB
...
SwapTotal: 4192956 kB
SwapFree: 1016052 kB
At this point, a new instance of Java would start up okay, and I was able to run my application.
(Obviously, for me, this was just a temporary solution; I still have an outstanding task to do a more thorough examination of the processes running on that machine to see if there's something that can be done to reduce the nominal memory utilization levels, without having to resort to stopping applications.)
Error :
For the error, "error occurred during initialization of vm could not reserve enough space for object heap jboss"
Root Cause :
Improper/insufficient memory allocation to our JVM as mentioned below.
e.g. JAVA_OPTS="-Xms1303m -Xmx1303m -XX:MaxPermSize=256m" in jboss-eap-6.2\bin\standalone.conf or "JAVA_OPTS=-Xms1G -Xmx1G -XX:MaxPermSize=256M" in jboss-eap-6.2\bin\standalone.conf.bat which is nothing but JVM memory allocation pool parameters.
Resolution :
Increase the heap size. To increase the heap size,
goto -> jboss-eap-6.2\bin\standalone.conf.bat or jboss-eap-6.2\bin\standalone.conf
change ->JAVA_OPTS="-Xms256m -Xmx512m -XX:MaxPermSize=256m" where -Xms is Minimum heap size and -Xmx is Maximum heap size.
Usually its not recommanded to have same size for min and max.
If you are running your application from eclipse,
Double click on the server
select 'open launch configuration' you will be redirected to the window 'Edit launch configuration properties'.
In this windown goto the tab '(x)=Arguments'.
In VM Arguments, define your heap size as mentioned below
"-Dprogram.name=JBossTools: JBoss EAP 6.1+ Runtime Server" -server -Xms256m -Xmx512m -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true
I recently faced this issue. I have 3 java applications that start with 1024m or 1280m heap size.
Java is looking at the available space in swap, and if there is not enough memory available, the jvm exits.
To resolve the issue, I had to end several programs that had a large amount of virtual memory allocated.
I was running on x86-64 linux with a 64-bit jvm.
I had right amount of memory settings but for me it was using a 64bit intellij with 32 bit jvm. Once I switched to 64 bit VM, the error was gone.
If you're running 32bit JVM, change heap size to smaller would probabaly help. You can do this by passing args to java directly or through enviroment variables like following,
java -Xms128M -Xmx512M
JAVA_OPTS="-Xms128M -Xmx512M"
For 64bit JVM, bigger heap size like -Xms512M -Xmx1536M should work.
Run java -version or java -d32, java--d64 for Java7 to check which version you're running.
Assuming you have enough free memory and you setup you JVM arguments correctly, you might have a problem of memory fragmentation. Check Java maximum memory on Windows XP.
Anyway, here is how to fix it:
Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System Variables->New:
Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M
OR
Change the ant call as shown as below.
<exec
**<arg value="-J-Xmx512m" />**
</exec>
It worked for me.
Error occurred during initialization of VM
Could not reserve enough space for 1572864KB object heap
I changed value of memory in settings.grade file
1536 to 512 and it helped
Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System Variables->New:
Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M
In case you are running a java program:
- run your program in a terminal using the correct command for linux it would be 'java -jar myprogram.jar' and add -Xms256m -Xmx512m, for instance: 'java -jar myprogram.jar Xms256m -Xmx512m'
In case you are running a .sh script (linux, mac?) or a .bat script (windows) open the script and look for the java options if they are present and increase the memory.
If all of the above doesn't work, check your processes (ctrl+alt+delete on windows) (ps aux on linux/mac) and kill the processes which use allot of memory and are not necessary for your operating system! => Try to re-run your program.
In CASSANDRA_HOME/bin/cassandra.bat you would find following configuration
REM JVM Opts we'll use in legacy run or installation
set JAVA_OPTS=-ea^
-javaagent:"%CASSANDRA_HOME%\lib\jamm-0.3.0.jar"^
-Xms**2G**^
-Xmx**2G**^
You can reduce 2G to some smaller number for e.g. 1G or even lesser and it should work.
Same if you are running on unix box, change in .sh file appropriately.
I got the same error and it got resolved when I deleted temp files using %temp% and restarting eclipse.
Sometimes it relates as
$ sysctl vm.overcommit_memory
vm.overcommit_memory = 2
If you set it to:
$ sysctl vm.overcommit_memory=0
It should work.
Replace -Xmx2G with -Xms512M or any greater memory size in cassandra.bat file in cassandra bin directory.
In my case I couldn't increase org.gradle.jvmargs=-Xmx... in gradle.properties beyond 1GB. It didn't work because I had two Java installation on my machine, one 32 bit (Gradle was using this one) and the other 64 bit. I resolved the problem by adding JAVA_HOME environment variable pointing to 64 bit Java.
No need to do anything just chnage in POM file like below
<configuration>
<maxmemory>1024M</maxmemory>
</configuration>
