Hi George,
No its just a plain server.
I used selenium and probe to check the issue.
Its definitely a Memory leak problem.

Hi Warren,
thanx, but I think session size is not an issue with 30 users since Tomcat has
about
2 GB memory.
But who knows, do you know a way to check the size of a session in tomcat?

Make a thread dump (kill -3 jvm pid). Information usually will be
written to catalina.out.
You can use jvisualvm tool to capture threads, memory snapshots, etc.

Hi,
we have the problem that tomact is slowing down after a while
until even the manager app becomes unusable.
Our System:

What can we do to analyse the problem?
Start by taking a thread dump to find out what's going on inside the JVM.

You need to investigate it with application developers. Examine all
threads and confirm whether application behaves correctly or not.

Just curious : how do you see that from the OP's stack trace ?
Just a guess, maybe I'm wrong:

Hi Christopher,
its not intentional but the myfaces App runs on the server for years now

A Wicket app that is not written correctly can suck up resources. Wicket
keeps track of pages a user has been on by serializing them, back
button support. If a page has references to other objects, it
serializes them and so on and so on. It can get real ugly real quick.
Wicket has many built-in
