Sure enough, I just did a tcpdump and caught a failed connection. Sure
enough, there's something weird going on at the tcp level. At the point
where the connection dies, it turns out that a packet gets lost, fast
retransmit is triggered, and the missing packet is retransmitted no less
than 6 times; an ack is never received for any of these 6 retransmissions.
Many seconds after that, one of the ends gives up and just resets the
connection.
I'll do more debugging tomorrow... right now it sure looks like this isn't
samba's problem.
