Hm. So that seems to indicate that, on windows, we're not properly recognizing dead sockets in the latch code. Could you check, IIRC with netstat or something like it, in what state the connections are?
netstat shows the socket is in FIN_WAIT_2.
Any chance you could single-step through WaitLatchOrSocket() with a debugger? Without additional information this is rather hard to diagnose.
Uh I sure can, but I have no idea what to look for :) Anything specific?
