Hello.

We started having a problem with one of our NetWare 6.5 (SP2) servers
all of a sudden yesterday afternoon when CPU utilization increased and
started running between 90 and 100 %. After a reboot without any
applications loading this behaviour is still present.

Looks like NSS is at the root of this. We have left the server running
for the last 14 hours to see if it is an NSS operation that will
finish, but no joy yet.

Any ideas would be gratefully received.

Thanks.
