    Re: worker thread

    That's not a good question because it points to the fact that if you need that many threads, then you don't have a good design.

    Since creating a thread requires a handle, one limit is the max # of handles available on the system. A while back (I think NT4 or Win2K) that used to be around 65K. Of course not all those would be available (because of other apps running, etc.).

    You have a more practical limit of several thousand, but still that doesn't mean that using that many is a good design. Investigate thread pooling via QueueUserWorkItem api.

    It's time to get out the undisputed king of troubleshooters.


    That's right, pull out "the debugger."

    Look for resources shared between threads that aren't synchronized.
