|Echoing what Jon Peatfield says, I have seen these errors on systems.
I've passed Jon's notes on to someone else to
try. I forgot to mention that we have IPMI cards
but have not yet done anything to them. So they
are in the systems, but unconfigured. (Is that
a problem?)
|Can I ask if you have IPMI on these machines?
|If that is so, I have a suggested fix.
|
|Use sysctl to set sunrpc.min_resvport to 665
|(IPMI cards use port 664 also)
|
|To make the fix persist after a reboot, edit
|/etc/sysctl.conf and add the lines:
|
|sunrpc.max_resvport = 1023
|sunrpc.min_resvport = 650
We tried this on 10 of the systems. When I started
the test loop, it went a little longer before failing,
then started failing again.
Also I forgot to note that this doesn't happen
with ssh.
