A symptom of orphaned processes is a lack of available system memory and/or swap space. The system administrator, and GEMPAK users should periodically check to see if there are abandoned proccesses and message queues. Typically, device drivers such as XW, GF, and GPS will be found in the system proccess table without any controlling GPLT or application program. When old GPLT programs are also abandoned, the device driver should be killed before the GPLT command.
If you find you have to kill proccesses, then you will have to manually remove the Inter Process Communications (aka IPCS, or message queues) that remain. The unix command: ipcs can be used to display allocated message queues. If you find there are users with queues allocated, without GEMPAK programs running, you can remove them using: ipcrm -q #.
