if your problem is still there:
JAVA_OPTS=$JAVA_OPTS -Xmx256m -Xms256m -XX:PermSize=256m -XX:MaxPermSize=256m
Please tune them for your environment :)

Thanks for your reply. But the problem isn't the size of the perm gen. The
problem is, that the classes within the permGen won't release after they are no
longer needed. So the PermGen will grow, grow and grow till you get a permGen

What do you mean by wont be released when they are not needed.? Permgen space
is used for loading class definition which is needed throughout the lifetime of

class loader, you should not see permgen space grow after
Sorry for my short uncleared explanation. When we do a hot undeploy of an
portlet (In case of updating it) and deploy the newer version the classes of
the old version wonât release from the perm Gen.

Which is why hot redeploy is not recommended for production, only for
development, I can't find it at the moment but there are plenty of explanations
about it and relate to some Sun JDK bug that has neven been fixed. Other JVM
handles permgen space differently.
Unless you redeploy a new
Hi, what we researched was a blog entry from Frank Kiviet
(http://blogs.sun.com/fkieviet/entry/how_to_fix_the_dreaded). The examples he
used could we completly reproduce. But the result isn't a bug in JDK...

We updated our JDK to 1.6.0_12 but we still get these errors. Is this a known
error in Portal or Jboss itself?
Thanks in advance.

Hi Thorsten,
I solved this issue for me by using a different Java implementation. Instead of
using Sun's JVM, we run the JBoss AS on Bea JRockit. Maybe this is an option
for you too.

Thanks for your reply,
but JRockit is not an option, as JRockit will load the classes in the heap
memory. But the classes won't be unloaded too. The heap space grows dynamicly.
But the perm Gen from the JDK doesn't grow.
