Thanks for the response, Tom. When looking at the system log,
the kernel was logging messages regarding IPX network name collisions
which apprently can happen when there are autoconfigured Win95 boxes
on the same subnet. These messages were flooding the log at a rate of
one every second or two...Even though #2 seems improbable, and just
glancing at the IPX kernel code didn't point to how that may have
caused a continual consumption of file descriptors, I'm willing to
blame the kernel on this (and me for using autoprimary and autointerface
options).
Thanks again,
Mike Mascari
