kernel lockd server not responding

[LearnLearnLearn]

I'm running 12.0.U6.

I see these in the client Apache logs on load balanced servers that are connected to an NFS share for their web pages.
When I see these in the logs, I don't see any problems with the share, all web servers still have access so I'm not sure what is going on.

I see these in the TN messages and console log;
Apr 7 17:09:54 truenas kernel[1810]: Last message 'NLM: failed to conta' repeated 3 times, suppressed by syslog-ng on truenas.local
Apr 7 17:15:01 truenas kernel: NLM: failed to contact remote rpcbind, stat = 5, port = 28416

Apr 7 17:23:27 truenas kernel[1810]: Last message 'NLM: failed to conta' repeated 3 times, suppressed by syslog-ng on truenas.local

Searching here and on the net, I find some mentions but nothing that seems to answer what is going on and all seem to be with freenas.

I'm not sure what other info to provide since that's about all I see for errors.
