no more application threads

Hello everybody,

from time to time I am having a problem with my application threads in my NW7 SPS10 portal.

I have already checked some other forum entries, and found some hints what I can check, but maybe someone of you has observed something similar and already has a solution.

My application threads all get kind of locked, and they all work with the same application and are waiting for monitor entry.

When now clicking through the threaddump viewer, I can identify this one as the one which is locking them (almost) all:

This application blabla uarf.services is more or less a little extention to UME which is writing some statistical data into tables, which are accessed with a jdbc connection pool.

Anyone seen anything similar yet, or any ideas?

Thanks a lot and cheers
