[jcifs] NTLM HTTP Filter loses connection?

OK, I'm using a slightly modified NTLM filter for my webapp, based upon 
v1.2.8 code.  It works great for the most-part.  However, under some load, 
and I have not yet determined exactly what -- we're in our TEST Env right 
now -- for some reason it starts to lose its connectivity to the domain 
servers.  Once it does, it seems that none of the threads in the app server 
(or filter) will work.  A restart seems to correct the problem immediately.

A snippet of the log is below.  I would appreciate any guidance in how to 
further troubleshoot or ideas on what might be going wrong.  Thanks very 
much in advance!
