I ran a script on MATLAB and it worked fine, when i want to run the script again, then MATLAB stuck in busy! i found a file "hs_err_pid1124" in the directory i works in it contain the following:
A fatal error has been detected by the Java Runtime Environment:
#
# java.lang.OutOfMemoryError: requested 16384000 bytes for GrET in

space?

My computer RAM is 4G, i increased the System Swap Space, but still the problem not solved!!
Thanks,
The most likely suspect here is your code. I would expect you to do something strange (opening a file, and not closing it later?! Reading each file into a continiously growing variable?!).
However, without code this is hard to diagnose.
Here is what you can do:
Evaluate the visible memory usage: Put a breakpoint somewhere halfway through, and inspect the size of the largest variables. Also check the total size. (If the error is a regular matlab error, you could also use dbstop if error)
Persuade matlab to release memory: If step 1 yields nothing, you may actually be doing things right, but perhaps matlab does not manage its memory properly. This is rare, but occurs sometimes when repeating simple tasks a lot of times. In this case you can place the pack command somewhere in your code. Probably it will help.

I have since the use of Atomicorp ASL Web and the like big problems with the JAVA memory under Centos 7.4. I have already tried many solutions from this community, but unfortunately nothing leads to success. Could you please help me.
I get this error message when I want to install Confluence App from Atlassian.
./atlassian-confluence-6.9.0-x64.bin
Unpacking JRE ...
Starting Installer ...
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x0000039f25000000, 2555904, 1) failed; error='Operation not permitted' (errno=1)

I realize that it's up to Centos OS and the root server. The root server has 64 GB of RAM and Atlassian apps need about 2-4 GB of RAM on average. I certainly have free RAM left. But as I can tell JAVA, I can not get it.
Which logs do you need or which SSH commands do I have to check? Thanks in advance.
P.S.

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

can anybody help me.
This means the Java runtime has a severe bug (it tried to access memory of other processes) and your application has somehow triggered it.
The next step is to see which shared libraries you have added to the process. Maybe there are newer versions.
If you use Oracle, use the pure Java thin client instead of OCI.
Maybe you have found a real bug in your version of Java. Try to upgrade to the latest version. If that doesn't help, file a bug report.
I got the similar issue. I was able to fix it. HotSpot Virtual Machine tries to access memory of other processes. Make sure you use same JVM for build compile and also your eclipse is using the same JVM as you build tool.
I got same problem, but resolved by following below steps:
Right click on project, select build path
Remove java jre library
again add the default java library
clean and publish the server
This is the first time I am in this situation with Java.
Java just core dumps with the following error:

when I tried running it on a mac os, it core dumps at the same place (the JREs must be different)... so it must be something related to the code. I have no idea how to debug this, this is not an exception, and the log file specified up there does not give me much information. Any ideas what I can do about it to find the bug?
The /tmp/hs_err_pid4327.log file should contain a stack trace of where the core occurred. Unless you are making a JNI call, it is probably a Java bug.
The core dump is telling what you should do...

A quick look makes me think this is already reported.
The bug probably isn't in your code, per se. It's most likely an environmental issue - perhaps a JVM bug, perhaps some unusual condition, and most likely, both - a bug that occurs rarely, under an odd circumstance.
Google for the key elements in the message (e.g. "safepoint.cpp:100"), look at the other reports, and look for things you have in common or workarounds that may apply. In this case, one set of reports suggests that heavy multithreading may contribute to the problem.
Check if you have a hprof file in your application directory. Optionally you could dump at will using
jmap -dump:file=<file_name> <pid>
and then analyze the dump using MAT http://www.eclipse.org/mat/
You could also consider other tools quoted here :
Tool for analyzing java core dump
I have been working on a large java application. It is quite parallel, and uses several fixedThreadPools (each with 8 threads). I am running it on a computer with 2 cores, each with 4 processors. My program is analyzing large sets of data, and the analysis is saved (serialized) after every set, though it works across data sets, and so is re-loaded every time I run a new one (and then saved).
My problem is this: after running 4-5 data sets (takes about 2 days, and I'm pretty happy with my coding efficiency) it will crash, after exactly the same amount of time on the 5th set (no matter which data set I use). The program is repetitive, and so there is nothing new in the code going on at this time. It is reproducible, and I am not sure what to do. I can post the full error log if that would help... I understand that this problem is ambiguous without a lot more detailed information, but if there are any go-to suggestions, it would be greatly appreciated.
I have been testing different settings to see if anything helps, and right now I am running with the following arguments.
-Xmx6g -Xmx12g -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC
Thanks,
Joe

Just a hard guess...
Might be it is not able to create more files
if you are running this in linux Try running
ulimit -c unlimited
Before you run your java program... This should help in two ways
It should increase the file creation limit
If any error occurs it will create the Core dump.
See how many file IO it is using while the program is running.
I'd instrument it with something like Visual VM. It'll show what's happening in memory, threads, CPU, objects created, etc. in real time as your app runs.
The nice version that I have is for Oracle/Sun JVMs only. There's one that ships with the JDK, but I don't believe it shows as much detail as the version 1.6.3 with all plugins installed.
Just add -Dorg.eclipse.swt.browser.DefaultType=mozilla in eclipse.ini file .
