How can I fix this? What you describe as "only" 50% cpu, I am guessing is actually the process hogging 100% cpu on one core of a dual core machine? i.e. your problem isn't underutilisation, it's something running away. Did you build PRC tools yourself from source? Have you asked if they've seen anything like this on the PRC mailing list? cheers, DaveK -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
