Situation
This is an abend that was intentionally added in the
released versions of NSS code. It is a debug check that
validates the previous and next node's link for each node that is
being de-queued from a linked list. If the node's next node
does not have a previous pointer pointing back correctly to the
node being removed, or if the node's previous node does not have a
next pointer pointing to the node being removed, then this abend
happens.
This check catches memory corruption before it can propagate
further in the file system. The NSS file system team at
Novell is serious about tracking down and eliminating all
forms of memory corruption with the NSS file system as early as
possible in the chain of events, and these types of checks help
with that process.
Resolution
Novell has used this specific abend to find and address issues
with NSS. In NetWare 6.5 Support Pack 7, a fix for a single
type of issue that caused this abend was included. This fix
in Support Pack 7 does not infer that all issues of this type
have been eliminated, or that this abend will not happen
again.
