Make sure your client is sending an Unbind request and closing the TCP
session.   Just dropping the connection will cause significant
delays at the server in freeing associated resources.

Differ codes are aggravated by different problems.   Of course,
both 1.2 and 2.x don't deal with resource allocation failures well
and this does need to be worked.  It's also possible that 2.0
new connection manager and thread pool is acting up.
