This is from the client side: http://www.codemonkey.org.uk/junk/tcp.out
Wireshark picks up some of those packets as being 'malformed', which
could be a clue ?
Something else of note which I hadn't seen before, usually things lock
up just after that first oops. For some reason, today it survived
a little longer, but things really went downhill fast.
After that first oops scrolled off the screen, and I saved the wireshark
output to disk, I got this..
