Hi, I have a VB .NET 2003 Windows appl. Application is multithreaded
handling 8 ports. The number of handles keep growing when monitored
thro' the task manager & we reach to a point that the server should
be restarted. Even an application restart doesn't help. Any known
issues on this subject

Increase in number of handles

What do you mean by 'number of handles' A handle, to me, is an unmanaged resource, which means you're completely responsible for it.

It sounds like your code is not managing it's resources properly.
