Thank you very much for your answer, Dieter.
There are 2 entries from in the DeadlockDebugger's output that may block

After I called the URL that is shown in those 2 threads
(/VirtualHostBase/http/intra:80/intranet/VirtualHostRoot/projects/index_DE)
these entry will not disappear from the DeadlockDebugger's output.
Maybe they cause the busy loop.

I reaööy don't know which part excactly cause the loop since there are 
some Silva-CMS-specific calls.

Regards
Nico
