Using the attached pure java server and client, I can reliably reproduce
the bug on JDK 1.5.0_17, on my Windows Server 2003 box.

After approx 8000 iterations of the client, the server crashes with the
following exception.

Exception in thread "main" java.io.IOException: Unable to establish
loopback connection

After the crash, when I issue the command "netstat -ano", I get
thousands of sockets, in the state "TIME_WAIT", and pid of 0:
