You must be using commons-daemon's procrun, otherwise known as the
Windows service wrapper. That process creates (and possibly locks) the
PID file for Tomcat.

You may find users here who know the answer to your question, but you
might have better luck posting to the commons mailing list to ask there.

I suspect it's something silly like holding-open the PID file instead
of writing to it and then closing it.
