Backup Exec 7.3 Errors

I have a Windows NT 4.0 Server w/ SP6a on which I am running Veritas Backup Exec v.7.3 Every once in a while (every couple of months) it will start throwing Dr. Watson errors up occuring in BENGINE.EXE. When I look in the Dr. Watson log, the error says that the error occurred in BENGINE.DBG.

It says that it’s an access violation 0xc0000005.
Veritas’s Knowledge Base didn’t have any relavent information on the error.
