NFS dies and stops responding

[einsteinagogo]

Thanks for your reply, this is Core.

I googled and read many NFS died issues on previous versions.

I’m not sure if it’s related to

Stability Isues with TrueNAS Core server

famous last words! NFS just stopped today! All hosts had the export mounted, and just lost access to datastores. Checking NFS 4.1 not responding, nothing in any of the logs as to why./ Trying to stop and start NFS hangs. All networking is fine and okay, no jumbo frames and this is on the older 1GBe. So the initial problem we were trying to solve, has returned. No access was being performed to the storage.

but it doesn’t play well if NFS just dies!
