I have running xsp2 or mod-mono-server2, where i start my webapplication. After
some request, after a minute a thread is started which never stops. After
another minute another thread is started which never stops, and so on.
After a minute i did a thread dump on xsp2, which is shown below.

Please tell me what the problem is.
