We are running it with sec=krb5p and are getting these errors (soft lockups) at the end of this mail across all the nodes causing them to be unresponsive after. The OmniOS server doesn't report anything wrong in the logs. I have submitted a ticket to Red Hat about this already but since it happens on all my RHEL clients at once and references the same OmniOS server (172.19.0.98) then it may have something to do either Omni NFS server or the interoperability of the RHEL NFSv4 client and the Omni NFSv4 server.
