I am new to ElasticSearch, but already in trouble.
My configuration:
Windows 7 Enterprise 64 bits
8 Gb RAM
I am unsuccessful at simply starting the instance, using elasticsearch.bat :
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.
Adter exploring SO forums as well as ElasticSearch support pages, here is what I tried:
setting min and/or max heap memory (using SET ES_MAX_MEM and SET ES_MIN_MEM on the command line before calling elasticsearch.bat) to various values, from 256m/512m to 256m/3g ==> no change in error message
setting heap size (using SET ES_HEAP_SIZE on the command line before calling elasticsearch.bat) to various values, from 256m to 3g ==> no change in error message
uninstalled my Java 7 environment and fresh installed Java 8 64 bits (checked through java -version on the command line) ==> no change in error message
Surprisingly enough, I can't seem to find any logging information (no 'logs' directory present in %ES_HOME% where the elasticsearch.org documentation states it should be...)
Would anyone point me to the right direction to get the thing up and running?
Thanks a lot
Finally got it sorted out by forcing JAVA_HOME to point to my fresh Java 8 install (seems 'java' command resorted to old java install although the Java 8 installer claimed it had cleaned previous installs).
Thanks a lot

About the following message:
Could not reserve enough space for 3145728KB object heap
I need some tips to understand what's going on
Points & Observations:
Running over Windows 10 x64 (16G Memory)
It only happens using this distribution: https://jdk.java.net/java-se-ri/8-MR3
It works fine using the build from AdoptOpenJDK: https://adoptopenjdk.net/?variant=openjdk8&jvmVariant=hotspot
At pom.xml, I've tried to add the following line: <extraJvmArgs>-Xms1G -Xmx4G -Xss1M -XX:-UseGCOverheadLimit -XX:MaxHeapSize=4G</extraJvmArgs>. But it "complains" The specified size exceeds the maximum representable size. (The original Xmx and MaxHeapSize was 3G)
Main Objective: To compile a project that was done previously using Oracle JDK8 with the Open JDK8
Any "lights"?
------ Edit
arg -d64 returns Error: This Java instance does not support a 64-bit JVM.
Maybe it's 32 bits the compilation from Java website?
I am using alloy4.2, and I am not able to tell it to use more memory.
I am not a Java expert and I suspect the problem is in how I'm configuring Java.
I am using OpenJDK Runtime Environment 1.8.0_131.
I have also tried 1.8.0_151.
My VM is running in Ubuntu x64.
Under the Alloy Options tab, Maximum Memory To Use is always stuck at the default of 768M.
I am using a VM that has 16G of memory available.
I have tried setting the Java stack parameters
-Xms1g and -Xmx8g
at the command line when I invoke Java, and also using the "export _JAVA_OPTS" to no avail.
Java says it is "picking up" the Xms and Xmx values and when I run
Java -XshowSettings:vm it shows that I have a max heap size of approx. 7.9G.
But Alloy doesn't let me increase the memory beyond the tiny minimum size of 768M. Any idea what I am doing wrong?
The numbers are hardcoded in Alloy although 4.2 should have 4Gb included? (There are a number of variants of 4.2 out there I think.)
We're working on creating a 5.0.0 version at the moment but that is not really publishable yet. You can download a snapshot JAR from:
https://oss.sonatype.org/content/repositories/snapshots/org/alloytools/org.alloytools.alloy.dist/5.0.0-SNAPSHOT/
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 have a DSpace server, after uprading from version 4.3 to 5.1, it constantly stops working after some hours with following error:
java.lang.OutOfMemoryError: Java heap space
I've read answers to the same questions, but they didn't help me.
My JAVA_OPTS: -Xmx4096M -Xms4096M -Dfile.encoding=UTF-8 -Dsun.jnu.encoding=UTF-8
Here are my logs:
dspace.log.2015-04-21: http://jpst.it/ylU4
tomcat7-stderr.2015-04-20.log: http://jpst.it/ylTN
localhost_access_log.2015-04-20.txt: http://jpst.it/ylTT
I searched the internet for a solution and could not find one, does any one have a clue?
Your tomcat log file quite clearly says that it isn't using the JAVA_OPTS you're passing in:
INFO: Command line argument: -Xmx256m
In my experience, DSpace 5 needs at least 512MB; your 4GB look a little excessive unless your DSpace instance is very big / gets lots of traffic.
You aren't telling us what operating system you're using, so it's hard to give advice on how where to set these properly. Start with your tomcat startup script and/or the tomcat configuration files. On my Red Hat Enterprise Linux 6.6 boxes (with tomcat6), the correct place for the memory settings is /etc/tomcat6/tomcat6.conf.
I am getting below error on starting SonarQube:
Error occured during initialixation of VM: Could not reserve enough space for memory heap
Also modified wrapper.conf underSonarQube conf folder, but didn't work.
Also changed java version: Java 8 to Java 7, didn't work
You do not enough available memory to run SonarQube. Try closing some applications.
If this is not enough check whether SonarQube's startup script specifies the amount of memory required, e.g. with options like -Xms=??? -Xmx=???. These indicate roughly the minimum and maximum amount of memory Java will acquire. Note the actual values and check with the task manager if you have enough memory available.
Issue was with version mismatch of plugins installed in sonarqube. I deleted jars for all plugins except java. This solved the issue.
I figured it out from sonar.log
Thanks
Its due to lack of memory. if you are trying that with ANT try the following
set ANT_OPTS=-XX:MaxPermSize=128m
