java.lang.OutOfMemoryError: PermGen space (RichFaces 3.3.0.G

marcos_aps Apr 13, 2009 9:54 AM

Hello, everybody!

First of all, that's what I'm using for development:

- JBoss 4.2.3.GA
- Java 5 Update 18
- RichFaces 3.3.0.GA
- Eclipse 3.4.2

This is the first time that I'm trying RichFaces, but I'm constantly getting this error (I'm running the application in Eclipse):

I've already changed the default Eclipse's configuration for the JVM from this:

-vmargs
-Xms40m
-Xmx512m

to this:

-vmargs
-Xms512m
-Xmx1024m
-XX:MaxPermSize=256m

I also change JBoss memory configuration in run.bat from this:

set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m

to this:

set JAVA_OPTS=%JAVA_OPTS% -Xms512m -Xmx1024m

and, even though it has got a little better, I'm still getting the error. This
is my configuration for RichFaces in web.xml:

<filter>
 <display-name>RichFaces filter</display-name>
 <filter-name>richfaces</filter-name>
 <filter-class>org.ajax4jsf.Filter</filter-class>
</filter>

<filter-mapping>
 <filter-name>richfaces</filter-name>
 <servlet-name>Faces Servlet</servlet-name>
 <dispatcher>REQUEST</dispatcher>
 <dispatcher>FORWARD</dispatcher>
 <dispatcher>INCLUDE</dispatcher>
</filter-mapping>

So, I'm not using skins. The machine where I'm working has 1GB of RAM memory.

What can I do to get rid of this out of memory error?

Thank you.

Hi Marcos,

Add -XX:MaxPermSize=128m to JBoss startup script and try.

Thanks for you replay, nbelaevski.
I made the change suggested by you, but I'm still getting the error after more or less 8 redeployments of my application to the server. What about the other memory paramets configuration in JBoss, -Xms and -Xmx ? The default values in run.bat are:

JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m

What about the Eclipse configuration too? The default values are:

-vmargs -Dosgi.requiredJavaVersion=1.5 -Xms40m -Xmx512m -XX:MaxPermSize=256m

Do I also have to change these?

Eclipse configuration does not affect JBoss. -Xmx and -Xms won't solve your issue also. Are you using any third-party libraries?

The only library that I'm using in my application, besides RichFaces, is Apache Tiles (version 2.0.5).
I must say that when I was not using RichFaces I also had the out of memory problem, but after more or less 70 or more redeployments in the same session in Eclipse. Now the problem appears just after more or less 7 or 8 redeployments. So RichFaces added a lot of things to the memory.

I run RichFaces and about 18 other libraries in my app. I havn't counted my redeployments using netbeans, but I can go a least 4 hours before restarting JBoss. I have 3G of ram and running Ubuntu. Here's my JBoss flags:
JAVA_OPTS="-server -Dprogram.name=run.sh -Djava.net.preferIPv4Stack=true -Xms1g -Xmx1g -Xmn128m -XX:PermSize=384m -XX:MaxPermSize=384m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled

Hello, Tom!
I have tried your JBoss configuration and I'm still getting the error early.
My machine runs Windows XP Update 3 and has 1GB memory. Maybe I have to increase the memory, but before that I think I'll switch from RichFaces to the Prototype library alone as I only need basic Ajax support in a few pages for the moment. I'm aware that RichFaces is a great technology and I would like to use it, as it would give me a great gain in productivity, but this memory problem just doesn't let me work. Thank you.
