out of memory error occurs while redepolying.

raghu88 Oct 9, 2012 1:29 AM

Hi i am new to the jboss,help me how to solve this issue

whenever i redeploying my project(more than once) it gives out of memory error ,after that i stop the server and again starts and then redepolying my project,it consumes a lot of time for me and redepolying and server statrting takes too much time.

my memory settings in run.conf batch file

JAVA_OPTS=-Xms128M -Xmx512M -XX:MaxPermSize=128M.

Help me how to avoid this issue,and how to reduce the starting and redepolying time?

Thanks,

Raghu.

It will help us to help you if you provide more informations than that. (i.e. JBoss version, stacktrace)

From what I can see you use 512M memory which sounds less, the GC might become in trouble during redeploy. Also the PermGenSize might be the issue.

I am using jboss 6.1.0 and Stack trace:

wdfink Oct 9, 2012 5:38 AM (in response to raghu88)

In that case you might try '-XX:MaxPermSize=256M'.
You can watch the PermGen via vconsole or jstat command-line tool (included in the java distribution) i.e. 'jstat -gccause'

Hi Fink,

   The probelm is not solved again i am facing the issue. I was changed my PermGen space to 256 and 512 also but still not resolved.It is highly embarrssing me pls help me.

6. Re: out of memory error occurs while redepolying.

wdfink Oct 20, 2012 5:33 AM (in response to raghu88)

You should check the PermGenSpace (use jstat jconsole ...) if it is increasing after each deploy I suppose you have a bug in the application that unwanted references are stored or you may find a bug in AS6.

If the PermGen is increased you can use a profiler (NetBeans JProfiler) or a simple heap dump to inspect the objects and with such information you should be able to find the owner of the reference.

nikem Oct 23, 2012 4:34 AM (in response to raghu88)

If you recieve java.lang.OutOfMemoryError: PermGen space on redeploys, that most propably means classloader leaks. In this case increasing PermSize will just delay the crash, not prevent it. You can read about this "pseudo-solution" here: http://plumbr.eu/blog/busting-permgen-myths . The only way to solve this problem is to find the cause of the memory leak and fix it. I can recommend Plumbr for this task.

I think that these values are lower

JAVA_OPTS=-Xms128M -Xmx512M -XX:MaxPermSize=128M.

TRY so

JAVA_OPTS=-Xms1024M -Xmx1024M -XX:PermSize=316M -XX:MaxPermSize=512M.

i started jboss through run.batch file instead of in myeclipse ,after that i redepolyed my application.It is working fine.But i shutdown the server and then starts server in eclipse i tried again but it is giving out of memory error again...

I suppose there should be settings for the server JVM in exlise as well
