Will not print from Certain Queues

I’m running Novell 4.10; we have a strange issue. A couple of the queues that are serviced by our print server will not process the jobs unless you unload and reload the pserver. This only happens to 2 queues, all the others being services by the pserver will spool the jobs to the printers fine. We deleted and recreate the queues that we are having a problem with, but the problem still persists. If you have any suggestions, please help. Thank You, Mike Scott
