Yes, I know.  The work-around in the bug report specifies which ports to 
exclude, but it doesn't include some of the ports you saw in your logs, 
so it won't solve the problem entirely.  If you instead specify the 
ports that are allowed, and use a higher range of ports, the work-around 
should be more reliable.
