Job Engine System Service FAILS REPEATEDLY!

All of a sudden I'm getting errors that the Job Engine System Service is failing.This used to only happen once in a blue moon, but now it happens every 45to 60 minutes.I have applied all the Upgrades and Patches available for Backup Exec forWindows Servers 9.1 with no resolution.I have followed all the suggestions from the Knowledge Base too.The only way I can get Backup Exec to complete any jobs is to set the JobEngine System Service to auto restart through Windows, but this causes somejobs to freeze.Any help would be appreciated...
