java.lang.OutOfMemoryError: PermGen space

[Chad Shryock, modificado hace 17 años.]

Any one see this before:

2006-11-22 22:10:57,132 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/].[jsp]] Servlet.service() for servlet jsp threw exception
java.lang.OutOfMemoryError: PermGen space
2006-11-22 22:10:57,133 ERROR [com.liferay.taglib.util.IncludeTag] java.lang.OutOfMemoryError: PermGen space

Is this because I need to give the JVM more memory? Any ideas?

This is displayed on the Admin Portlet:
Uptime: 00:58:27
Free Memory: 118,310,032 Bytes
Total Memory: 259,534,848 Bytes
Maximum Memory: 530,907,136 Bytes

Thanks in advance,
Chad.

add -XX:MaxPermSize=128m to your jvm options

[Chad Shryock, modificado hace 17 años.]

Thanks! This seems to have fixed the problem.

Question: where in the documentation would I have found this? That way I don't have to keep asking questions.

Thanks,
Chad.

This particular item is not in there. But our wiki does have a lot of useful information. Actually if you could update our wiki for this particular item we'd appreciate it!

http://wiki.liferay.com/index.php/Liferay_FAQ

Search for "What do I do if I am getting Out of Memory Errors"

[Andres Serra Fernández, modificado hace 15 años.]

In that Wiki says what we have to modify de file named catalina.bat, but I can´t find these terms in the file, I found it in setenv.bat, but the problem persists.

Any other idea? I'm using lomboz and liferay 5+tomcat 6.

Thanks!

Are you lauching Liferay from Lomboz? If you are you need to change the launch parameters for the server in your IDE not in tomcat's startup scripts.

[Michael Saechang, modificado hace 15 años.]

you would modify the JAVA_OPTS in the catalina.bat

example.

set JAVA_OPTS=%JAVA_OPTS% -Xms512m -Xmx512m -XX:MaxPermSize=256m -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file="%CATALINA_BASE%\conf\logging.properties"

That page does not exist anymore. Or does it?

Update for Liferay 6.1: 128m in MaxPermSize option is not enough. Setting it to 256m will solve the problem.

[Tal M, modificado hace 12 años.]

I set it to 512 or 1024 but the problem persist.
I also monitored the liferay tomcat process using jconsole, and seems there is a memory leaks since the perm gen space raises continuously.

Is that a known CRITICAL in 6.1?
we must have a solution for this problem.

Thanks

I believe I'm finding the same symptoms as you, Tal. For Liferay 6.0, I'm consistently getting a "java.lang.OutOfMemoryError: PermGen space" on Tomcat startup.

After trying many JAVA_OPTS memory property combinations (XX:MaxPermSize, etc.) as high as 2048m, and even after removing all portlets except for ROOT, I still encounter this problem.

Has anybody found any workarounds or troubleshooting paths when XX:MaxPermSize is not working as a solution for the OutOfMemoryError?

Here is the exact stack trace:

Hi,

I am too facing some memory issues with Liferay 6.1. I have started new thread for same click here

Lets discus it here.

I have the same issue when running Liferay on Windows 2003 server. All is good when running the startup.bat, but if I try to run tomcat as a service - I get the java.lang.OutOfMemoryError: PermGen space error...Tried increasing the PermGen but that does not help.

[David H Nebinger, modificado hace 10 años.]

You have to consider how it's installed and how the service starts.

I use Tcat, and I have to go into the registry and tweak registry values to affect change (they do have a props file, but if I change that I have to use their start menu guy to make it stick, rather than service control panel).

Anyway, the point is you have to know what is involved when the service is started to ensure that your sitting is at the right place....

Hi Mike,

I have same kind of issue.

When try to run starup.bat, there is no issue but when i am using windows service option to run my liferay server.

The when i try to tun service, i am getting this error.. Please help me.

Any body help would be appreciated.

Thanks,
Babu.

Hi,

you can find documentation about starting tomcat as a Windows service here:

http://tomcat.apache.org/tomcat-6.0-doc/windows-service-howto.html

--JvmOptions is what you are looking for.

tomcat/bin setenv.bat


set "JAVA_OPTS=%JAVA_OPTS% -Dfile.encoding=UTF8 -Djava.net.preferIPv4Stack=true -Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false -Duser.timezone=GMT -Xmx1024m -XX:MaxPermSize=256m"

copy this instead above


set "JAVA_OPTS=%JAVA_OPTS% -Dfile.encoding=UTF8 -Djava.net.preferIPv4Stack=true -Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false -Duser.timezone=GMT -Xms1536m -Xmx1536m -XX:NewSize=256m -XX:MaxNewSize=256m -XXermSize=256m -XX:MaxPermSize=256m -XX:+DisableExplicitGC"


because of this symbol, dowload this file,

set JAVA_opts



good luck

Hi Generally when we work with eclipse

We will create run time env servers

the actual configuration which we have done for server some time it may not applicable to server we create in eclipse.

in general for tomcat we use setenv.bat or setenv.sh to add our server configuration in the we increase paramgen space and jvm heap size

in jboss standalone.bat or standalone.conf to to add our server configuration in the we increse paramge space and jvm heap size

but when we create server in eclipse using server view some time those configuration may not use server instance which create by eclise thne

go to server views and double click on your server then it will lanch view in eclipse click on open lanch configuration then change settings
