Have you run CheckNet on the net?  It sounds like some lost data, or collisions
are killing your connections.  The software drivers for the FlashTalk boards
are probably maximized to keep from tying up the pc waiting on notoriously slow
laserwriters to print.  Given some parameter of default time, the lost packets
timeout the boards.

The lost or collisions could be the unavoidable kind, but you could have a
mac with a bad appletalk chip (serial chip).  Then again, it may just be 
traffic across the bridges is tying things up.

Monitor the traffic between the two machines in question.

good luck
