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.]
