Subject Re: Clips offline

Hi Oliver

The stacktrace shows the java server socket that wants to accept a new 
connection but cannot, because it already ate all available system 
handles (files and sockets are treated the same).
Sounds like a leak, race condition or an attack.
Maybe someone @trialox got his bells ringing, but I do not know clerezza 
enough to have any idea what could be the cause.

on linux, you can check the system-handles that a certain process uses 
by typing:

ps aux | grep java ->  <pid>
lsof -p<pid>

Cheers
André
