George, Thanks for the reply! Yeah, a semaphore lock gets "stuck" and does not release which leads to the hung state. In general I do not see any semaphore locks for more than a second, so I don't think we are reaching any kind of maximum limits. (Even when the spooler does hang, it is only one semaphore lock that is held.) I am working with Rocket support; however, they have not been able to figure out why that lock doesn't release.... Thanks, Al
