I'm running 3.99.1 on an i386 laptop, with a wm0 network interface.
I was debugging a SIP problem, and needed to trace some traffic, so I
ran tethereal, and forgot to say "-p" to keep it from switching my wm0
into promiscuous mode. The output from tethereal made me think that
the other end had fallen off the net -- until Mozilla told me some
automatic refresh had failed, and I realized that it was actually *my*
machine that was without connectivity. All ssh sessions were hung.
After I stopped the tethereal run, connectivity came back. This is
completely repeatable, using either tethereal or tcpdump.
Does this ring a bell with anyone?
Don't ascribe to stupidity what can be adequately explained by ignorance.
