If the trace is on the packets coming in to the Domino server then it
doesn't seem like it would be the Domino server's card. But if they are
from 3 different sources and are showing up bad coming in to that card then
possibly there's a malfunctioning port on the switch/hub that the Domino
server's card is plugged in to? These are the worst sort of problems but
they feel great when you finally figure them out... be strong. ;)

And a reasonable guess, but the problem packets all seem to originate
somewhere else (three different sources in three different cases, so far)
and come to the Domino server. The questionable packets are being
captured before they touch the Domino server. Or are you suggesting that
the ethernet card in the iSeries is faulty and going nuts with these
packets where a good card wouldn't?

Re: Bad packets?
Maybe a failing ethernet card... just a guess of course.

Continuing investigations into the issue I asked about last week...
We have PTFs on order, so hopefully this will be cured when those are
applied, but just in case... Network guys ran packet captures against the
port where my Domino server attaches to the network. We are aware of
three timeouts occurring yesterday. Each timeout was accompanied by a
series of packets in the packet capture that didn't appear when there was
no timeout. They are continuing the capture today to try and verify that
they are related. They are using Ethereal as the packet analyzer.
The older version of Ethereal being used flagged these packets as "BAD
PACKET!" with a variety of other information. It also indicates that they
are using the Diameter protocol. The newer version of Ethereal flagged
the same packets as truncated, but didn't make any reference to bad
packets. It indicated that they were using DCE-RPC protocol. Both
indicated that the port being used was 1811 and 1812. The techs don't see
anything specific in the packets that would cause problems.
Does this sound familiar to anyone?
Thanks,
Patrick
