Still haven't heard anything on what this problem could be.

what we have found:

having sub interfaces on eth0:1 on a NAT box works perfectly
having sub interfaces on eth1:1 on a NAT box is *GAURANTEED* to
lock the machine up _EVERY_SINGLE_DAY_ at least once.

the card in all 3 of our machines is a dual ported:
01:04.0 Ethernet controller: Intel Corporation 82557 [Ethernet Pro 100] (rev 08)
Subsystem: Intel Corporation EtherExpress PRO/100+ Server Adapter (PILA8470B)
	Flags: bus master, medium devsel, latency 64, IRQ 11
	Memory at ff8fe000 (32-bit, non-prefetchable)
	I/O ports at de80
	Memory at ff700000 (32-bit, non-prefetchable)
	Capabilities: [dc] Power Management version 2

I believe the driver we are using is 1.11a but i also tried
a newer one with the same results(actually only tried
the with eth1:1 not with eth0:1).  

once we switched from eth1:1 to eth0:1 the machine in question
has not crashed or even had a single error in over  a month.
my original messsage:

on another note does anyone know of a mainboard that has
dual 3com ports on it? or a vendor that has a system(1U)
which does? the eepro(driver/chip/whatever) has prooven
time and again that its unreliable in the long term.
