I maintain it is network card - my reason see below

Elimination for success was only network (hardware) all software and OS
behaved consistently Plus see below

 This problem does not occur on the same machines when running FC1. I

With FC1 max file size (as U say) is 3m......whereas problem is with large
files and "on network"  -> again elimination takes us to network card.

 This problem only appears to occur with large files. I have two different

Is the control group same (identical)  for FC1 and FC3,      and has a mix
of small and gigsize files?
If UR sure that the same worked on FC1 then it would be worth to try using
network card's FC1 drivers on FC3 !!! and befriend Bugzilla.
(I recall a case<https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=161242>of
VGA monitors between FC3 and FC4.)

otherwise..

Please check specs of network card, even ur new cards may be of similar
specs (genre wise) as old cards - no offence but just check.
