[Samba] client hangs

[Doug Tucker]

Already been down that path.  I can't find a network issue anywhere.  
Our samba server itself is set up with a bonded interface which attaches 
to 2 different cards in the switch.  I've pulled each ethernet cable to 
see the results and there is no ping loss or interruption of any sort 
and shutting down the port at the logical level I see the same result.  
I monitor all of the switches and routers in our network with opennms 
and cannot find there, or in any of the logs any network interruption 
anywhere.  Additionally samba seems to be the only server affected.  We 
have 50 or so linux servers on the network that aren't experiencing any 
file server interruption.  As for the samba server itself, I moved some 
clients over to our backup and the problem follows them.

Sincerely,

Doug Tucker
