FC2 - Strange Ethernet Behavior

[John Krische]

Hello again to all

Followup info on the networking problem I'm getting on FC2 (connection 
speed plummeting for no apparent reason after ~1MB of sustained 
traffic).  I've managed to rule out our main router and firewall as a 
potential source, as the problem is appearing between hosts on the 
internal LAN, going through a very nice switch.  I've also ruled out the 
TCP Window Scale suggestion by Andy Green - tried various network ops 
(internal LAN) with and without scaling, no effect whatsoever.  I have 
further confirmed 100% that the problem is restricted to our FC2 boxes 
only.  We have a Debian box that is running kernel 2.6.7, same as the 
FC2's, and is using the same NIC model & module as at least one of our 
FC2's, but that debian system has none of these strange network behaviors.

Any other suggestions, anyone?
