I saw 5 of the following severity=5 errors in the Sys$log.err
(apparently I cannot attach stuff still so a portion of this abend is
below) about 20 minutes before the server abended, then it abended
again last night, same error.

A search of novell for:
"SizeOfAllocBlock detected corrupt preceding redzone for node 0xA872CD"

Produced:
Abend in NSSMU.NLM on NetWare 6 - TID10090662

Which says it is fixed with the NSSMU.nlm dated 11/19/03, which I am
using.

Any ideas?
