<br>
I am wondering if anyone else has experience running NFSv4 from OmniOS<br>
to RHEL (6.5) clients. We are running it with sec=krb5p and are getting<br>
these errors (soft lockups) at the end of this mail across all the nodes<br>
causing them to be unresponsive after. The OmniOS server doesn't report<br>
anything wrong in the logs. I have submitted a ticket to Red Hat about<br>
this already but since it happens on all my RHEL clients at once and<br>
references the same OmniOS server (172.19.0.98) then it may have<br>
something to do either Omni NFS server or the interoperability of the<br>
RHEL NFSv4 client and the Omni NFSv4 server.<br>
<br>
Thanks,<br>
