Error ID: 2009

Last Friday morning and this Monday morning:
When I get into work in the morning I always check on my backups:
Running HP Tapeware XE s.w. on a HP Surestore DAT24. The NT 4.0 SP6a server seems to have a service hung up. When I check Task mrg. it shows %100 CPU usage and the task Tapeware Running. When I check my event viewer I get: Error ID : 2009
The server could not expand a table because the table reached the max. I tried killing the tapeware service in services but it gives me an error that it is in use, then it shows as not running. I know if I re-boot I will be back to normal. Any one know what this Error ID: 2009 is ?
