In my server application this leak doesn't occur in windows xp, however on
windows 2003 systems the umdh dump shows a large memory leak that I can't
seem to trace.
The umdh log is below. It's weird the stack trace doesn't seem to originate
anywhere from inside my code and I have all the pdbs. Any ideas what is
causing this?
