Gee, this should be justification for a decent performance monitor??? I know
one that
easily detects looping processes and alerts on them.

Hello list,
I found the problem.
On the NFS client system, there was a VSFTPD process that had been
sitting there for a while consuming a large percentage of the CPU on
that system. I did a kill -9. On /var/log/messages, I received an
unexpected lock response message. When I looked back on the NFS server,
the lockd process was no longer consuming large amounts of CPU.
Thanks,
Ron

Hello,
Sorry about responding slowly. It seems that the new spam filter here
at work is filtering out some of the messages from the mailing list.
I did not notice the response until I went over to mail-archive.com.
can Hopefully the mail folks to find out why I did not get your
responses.
Brad,
When I upgraded this system to Service Pack 2, I put in a cio_ignore
statement.
Rob,
I opened a Service Request with Novell. The engineer suggested I do a
tcpdump to see if some other system was peppering this system with NFS
requests. There is, at the rate of about 1500 to 2000/second. (There
is a hipersockets connection between the two systems.)
Thanks for the information about CPU. I will need to file that away.
If there is anyone on the list who might know why an NFS client might
be making a few thousand requests a second. The entries are:
