With Tomcat4.0.3, client (50 threads) connect server, and each client thread repeats about 80 connections sequently. In the beginning, client thread can run well. But after a monment, client threw the following exception: java.net.BindException: Address in use: connect at java.net.PlainSocketImpl.socketConnect(N ative Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:320) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:133) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:120) at java.net.Socket.

I used "netstat -nap TCP" and found there are about 4500 entries, with status "TIME_WAIT". I wonder if client thread ran off all availalbe ports? But i learned that the maximum number of port is 64K.
Anyone knows the reason?
Thanks.
