I've had 11 servers running 6.5 SP3 for the last few years. I think maybe
1 server crashed in all that time. Now suddenly, 2 servers abended (1 of
them twice) in the last week. The log shows "Netware OS detected a rpblem
with the system while executing a process owned by NCPIP. It may be the
source of the problem or there may have been a memory corruption."

Any ideas about what's going on?
