java.lang.OutOfMemoryError: PermGen space

[tony.herstell1]

If I rely on Hot Deploy then I get this after a few times.

What are the recommended settings for the prod server?

I usually resort to always shutting down and starting the prod server.

Never get this on Dev server as thats all controlled by MyEclipse deployment I guess; i.e. I never deploy on Dev...

I use these:

-Xms128m -Xmx512m -XX:MaxPermSize=256m

With these settings I can run the full JBoss AS with the Portal 2.7 and Seam 2.0 deployed.

Tony, I assume you are using SunJDK ? This is afaik a problem with SunJDK, I tried hot-redeploying with Oracle BEA JRockit VM and never got OutOfMemory when doing so.

I would recommend doing cold deploy when deploying to prod in any case. Other things could go wrong aside from the PermGen Space.

[balanscott.balanscott.gmail.com]

We used the same parameters as above and have to invoke garbage collection a lot otherwise we will still get the PermGen issue. Our issue though seems related to the mass amount of EJB 3 based web services we are using.

Have a look here: Classloader leaks

This may not necessarily be from your code specifically but could be from some of the dependent libraries.

Also, from what I've read using JRockit VM does not solve the problem.  Instead of throwing PermGen exception, JRockit will keep eating up memory. Read the final post here

As per release notes from JBoss Enterprise Application Platform 4.3:

-Xms1303m -Xmx1303m -XX:PermSize=256m -XX:MaxPermSize=256m

Is this what you use?

[ericjava.eric.chiralsoftware.net]

I wrote an analysis of JBoss Seam PermGen use which might help.

[tony.herstell1]

Yes, thats how I am working.

Stop and restart!

Hi,

I have the same problems when redeploying my application (EJB3/Seam/Icefaces) on JBoss 4.2 on my Mac. On the production and test machines we use the BEA JRockit and there we never saw the problem, even on the test machines.
But on my Macbook, I often have the problem when I redeploy the applications during developpment. Increasing the jvm memory only postponed the error but did not solve it.
