Unisys/PTX 2.1 & error 25572

Hi. From time to time I get the following error in my logs: listener-thread: err = -25572: Network driver cannot bind a name to the port. System error = 5. Attempting to bring listener thread down This is normally during a restart; today was a situation where I had to yo-yo the engine to get some config parameters reset. I do a netstat -a and grep for the service name/number, but never do I find something else using that port. Obviously there is something hung up that makes the OS think that the service is still in use. So far, the only options have been to (a) wait, or (b) reboot, neither an attractive option for a production machine. (I have tried stopping and restarting all network services, to no avail.) Needless to say, due to the obsolete machine and operating system combination, we are stuck with 7.10.UC5. Thanks, David dcoburn@wvus.org
