Oh great pool of hardware and driver knowledge....

OK, so this is off-topic again, but this group is likely the most 
knowledgable source of info likely to have a handle on something like this.

I've got a pair of servers directly off a router/switch.  There is one 
problemmatic server/port interface, as shown in the MRTG page at 

If you notice, connectivity appears to drop every 30 min.  although 
subjectively it appears to happen more often (say, every 3 min or so...) 
for periods of 30-45 sec.

Hardware here is a Dell PwerEdge 650 with the onboard Intel Pro/E1000 
adapter and a 2nd Intel E1000 dual port copper adapter.

Software is RH9 with all current patches, Apache and the Minnesota 
Mapserver, plus PostGres/PostGIS running.

NFS services to the box die periodically and users are sayingthe web 
response stinks.

I've taken a couple of decent shots at the problem.  I'm hoping someone 
here might have a potential solution I can check out!
