[jboss-user] [Remoting] - Re: JBREM-877: New Socket Connection is being Created for Ev

Hi Vinay,

I'm looking at your thread dumps, and I don't see anything strange from the perspective of Remoting.  I see a bunch of Remoting ServerThreads in a WAITING state, which implies they're currently not in use.

The only exception I've noticed is in the server-stack.log file you sent me:

which seems to be related to your application code.  Could that be where you're experiencing a hang up?

Also, server-stack.log just has 355 threads.  That doesn't sound like enough for you to run out of threads.

I'm not getting the picture yet.
