Doug, thanks for the tip, I'll give that a try as I haven't been forcing
either card to 10Mbit or TP connections. I have added to the mystery
however and this is aggravatingly puzzling.
In my previous message I had mentioned that walking away fromt he console
for any length of time would cause the machine to generate the "No buffer
space" errors. Since then I've turned off my screensaver (Matrix from
KDE) and the system has stabilized completely; well almost completely. I
can still duplicate the buffer situation and I've still seen it occur when
doing fairly high bandwidth (for cable, not for ethernet) file transfers.
If I can manage to bring the xfer rate up to around 100K/sec total between
inbound and outbound I experience the "Out of buffer" messages within a
couple minutes. netstat -m doesn't show anything unusual. I am going to
try removing both NMBCLUSTERS and NBUF from my config and just use a
maxusers of 128 and see how that goes.
