We had a similar situation with a server here.
In our case, further investigation showed that the de0 interface was
reporting an error for nearly every output packet (via "netstat -ni").
A re-boot showed the same result (with respect to "netstat -ni").
This was a 100Mb/s interface, BTW.
I got a replacement Ethernet card to put in the machine; as I was about
to take the old one out, it seemed to me that the de card wasn't properly
seated... so I re-seated it & re-tried. Nope; immediately after
re-boot, 324 outout errors our of 325 output packets. :-(
Swapped in a fxp card... no LINK light at all. :-(!
Swapped in a different fxp; much happier:
[138] netstat -ni

(Note: ifconfig says "SIMPLEX", but the switch says 100Mb/s, full duplex.)
I've suggested making final improvements on the 2 other cards by driving
my truck over'em a few times in the parking lot....
Hope this is useful,
david
