printer queue gets stuck

We often encounter a similar problem ( Unix V R2 V2 on vax 8600 connected
to the would via ethernet LAN ).  I end up having to halt the print
scheduler, rm lockfiles, and restarting the scheduler.  We have finally
determined that often, whenever a NetCommander (print server) on our
LAN is rebooted that the scheduler on our Unix system will hose up.  The 
above always manages to restart everything.  Maybe this'll help -- maybe
it won't.
