We have experienced a phantom load average on a SPARCserver 670MP
running SunOS 4.1.2 on a couple of occassions now. By phantom I
mean that running top you won't see any unusually high CPU % numbers
for any processes or abnormal number of processes in the run STATE.
The problems were:
- a field in the NIS passwd file where the gecos field for gid had
nothing in it. Just '::'. Where is that script for a sanity check
of the NIS tables before you push them out...
- the most recent instance, we had a second machine whose filesystem
was NFS mounted on the SPARCserver which had it's rpc.lockd tip over.
Hooking up trace -p process# to active processes helped in
determining the source of the problem.
