Hi,
Your Permanent Generation is running out of memory, this is a special
space in the vm memory, where the vm stores all of its internal data
(classes, etc.). You should pass -XX:+PrintGCDetails to the VM to see
how much perm-space is used. If you have a lot of third-party-libraries
etc. your permanent space might be to small, adjust using:
-XX:MaxPermSize=<newvalue>
see here for options:
http://java.sun.com/docs/hotspot/VMOptions.html
regards,
Ingo

Hello,
I have many memory consuming apps on my tomcat server. I a lot pdf & excel
generation. So every other week I get this error
java.lang.OutOfMemoryError: PermGen space
I know the root of this error is that the garbage collector does not clean
up and memory allocated
for java object generation is used up. But what can I do about it? If I
allocate more memory I'm only postponing
the problem. So do I have to shutdown every day my tomcat server to ensure
the deletion of unused objects or
Will only a tomcat cluster help in this case? I also read the archives but
could not find any useful explenation.
I defined max memory usage for 2 Gig with the Catalina_Opts variable in my
start script. CATALINA_OPTS="-Xmx2048m -Xms1536m"
Tomcat 5.5.9
Java 1.5.0_04-b05
SuSE Linux ES 9
Cheers,
Pete
