NZDM Service failing due to timeout

Hello.
the J2EE Instance of one of our PI Systems does not come online anymore. The last thing that happens is that the NZDM core Service fails with a timeout (and with that taking down the rest of the engine)

As the NZDM is rather new and currently very PI specific area I hope to find someone else who has overcome this issue already.

Log entries are attached (copy & paste doesn't work here for some reason)

Thanks for thinking!
