Tested on pcAnywhere 9.2, it seems if you connect then disconnect
to pcAnywhere host service about 300 - 500 times the service will

stop responding. The only way to get it to respond is to restart
the service. The latest version of pcAnywhere is 10 and we don't
have it but I would imagine it has the same problems.

I was told that Alpha could not reproduce this but I can. The only
thing that I think I am doing different is the fact that I run a
tool called "IP Ultra Monitor 2000" that checks to see every 1 minuet
if the server is still up. One of the ports is 5631 (pcAnywhere host
service). I let the program run for about 2 - 3 hours and the port
is still open however if you try to connect with the pcAnywhere client
it will not connect.
