NW 6- sp5- TSAUP518 Backup Exec for Netware 9.1 Build 1158.9

We are experiencing this Abend (below) consistently on one of our HP ML370
G3 NW 6 servers- only on Monday nights during our full back up (between a
half hour and an hour into it)- the rest of the week we run differentials.
BE is up to the latest build- we also just updated our TSAs and SMDR
(TSAUP518)- We also ran HP diagnostics on the server to rule out any
hardware issues.
Any information on this issue would be greatly appreciated. Dennis Topo Jr-
