There is another problem which could cause this -- which is
running out of local port numbers. In all 2.0.x linux, there
are only 4k local ports, and once they are all in TIME_WAIT
you are doomed. I have a patch -- which I guess I ought to put
together, which fixes that problem as well. [By increasing
the number of local port numbers to approx 32k. This is not
a long term solution to the problem, which needs better handling
of TIME_WAIT sockets.]
