Upgrade to Centos 6. I have approx 20 jetway mini-itx boxes with a built
in 8139. I recently had all but 2 experience large packet loss problems.
Some of them were happily running C-5 for over 2 years. Upgrading them to C-6
solved it but I do not know why. I too would really like to understand what
is going on here.

In addition, I would like to know why I still have 2 boxes that are happily
running c-5.

I suspect that this is some kind of driver issue but I even tried upgrading
the drivers using those supplied by EL-Repo. The only thing that improved the
situation was upgrading to C-6.

FWIW, I use them as router/firewalls. They have a 3 port daughter board 
for a total of 4 Ethernet ports on them that I have recently switched to using
an Intel based chipset just as a precaution.

HTH,
