java.lang.OutOfMemoryError: PermGen space in Alfresco 2.1

Alfresco,We are trying out Alfresco 2.1 Comunity here and I'm impressed with the imporovements since 1.4, nice. After working on a clean installation for a while we got the following error:09:12:17,398 ERROR [org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/alfresco].[jsp]] Servlet.se

Try to increase amount of memory, for example for Windows and Tomcat you can set environment variable:

CATALINA_OPTS=-server -XX:MaxPermSize=256m
‍‍

I do not know if this variable works in Linux environment.
If value 256 does not work, change it.

Thanks, I was confused with the Java heap space, we changed that one before. I'll try this!

That is indeed the fix. We have only seen this before on JBoss (which loads a lot more classes than plain tomcat) - are you using JBoss? If not, do you have a lot of other webapps (i.e. a lot more JAR files) in memory? I'm interested because if this is a default installation on plain tomcat then we may need to increase the PermGenSpace value by default for 2.1.

Thanks,

Kevin

Kevin,

We are evaluation 2.1 RC on Tomcat, standalone. We did import the blog module AMP package and the WCM one almost from the start. I don't really remember if the problem also occurred before or after this but I don't think it would hurt adding a bit more memory from the start.

Kevin,

I, just today started getting the following on tomcat 5.5, Windows XP.

I also have a Linux version running…I will watch it on there.

Exception in thread "DefaultScheduler_QuartzSchedulerThread" java.lang.OutOfMemo
ryError: PermGen space
Exception in thread "http-80-Processor24" java.lang.OutOfMemoryError: PermGen space
Exception in thread "http-80-Processor25" java.lang.OutOfMemoryError: PermGen space
Exception in thread "http-80-Processor22" java.lang.OutOfMemoryError: PermGen space‍‍‍‍‍

I will increase the MAXPERMSIZE and see if it fixes it.

It will fix it. It can happen to any Java app that loads enough classes…
