I'm working on reproducing the Spread hanging bug reliably (as reported
here before) so that we can test switching to a hub and/or new router.
We need to see it fail before we can determine that changing out the
switch fixes it.
I believe I've got it isolated. Does the following spmonitor output show
the bug in question?
If so, how is that determined from the spmonitor output? (so I don't
have to bother the list with this again)
Now, I'm clear that Spread has hung here, and I'm about 99.9% certain
that this is the same bug (packets received out of order), but I want to
be 100% sure before we proceed.
