Client is having issue where their server is crashing anywhere between 2-3 per day and definitely overnight. There was a point where it would restart every time it crashed, now it just freezes at the Novell debugger stating the above message.

Server IBM X225
512MB ECC memory (more is being ordered)

NetWare 6.5 SP7
GroupWise 6.5
Backup Exec

Do I need to run DSrepair? this error just started showing up recently.
