-------------------------------------
Doesn't look that way as the stack trace posted indicates actual threads
waiting on condition objects and not just leaked handles.

> The number of CMS threads increases when we restart the message broker
> repeatedly. We have ten senders and ten receivers in out test. Every sender
> sends out 10-20 messages every second. We restart the broker every 1 minute.
> The number of threads in CMS grew from about 50 to 600 after about 15 hours
> of testing. The attached dump was created after we ran two hours of test.
> From the dump we find a large number of threads are stuck at the following
> place:
> Function Source
> ntdll!KiFastSystemCallRet
> ntdll!ZwWaitForSingleObject+c
> kernel32!WaitForSingleObjectEx+a8
> kernel32!WaitForSingleObject+12
