It may not have any effect but try changing the socket call to this:
socket.socket(socket.AF_INET, socket.SOCK_STREAM, socket.IPPROTO_TCP)
I recently wrote a non-blocking select loop server (in C) on AIX 4.3.3
and the program would run for hours then fail in strange ways. When I
changed the socket() protocol argument from zero to IPROTO_TCP the
problems went away.
It is a long shot, but it is worth a try.
