Hi Daniel,

in the thread dump you sent to me i found the thread which holds the lock you mentioned above:

This thread is also hanging in a socketRead0() which is triggered from 
org.jboss.remoting.transport.socket.MicroSocketClientInvoker.readVersion(MicroSocketClientInvoker.java:1077)
This is the point all threads are hanging even on client side. But i have no idea why the inputStream cannot be read.

You mentioned that the local message processing works, so i assume there is no issue with the database.

Regards,
Matthias
