[ovirt-users] Communication errors between engine and nodes?

Mon Mar 16 06:34:21 EDT 2015

Received the "heartbeat exeeded" continuously this morning (seems to be quiet again for now).
VM's still continue to work correctly and the storage domains (NFS shares) are still connected and reachable on the nodes, at the exact time that this issue is happening.

Contacted our network engineer to see if he could see a load increase on our network, or could see any latency, errors, etc.
Unfortunately he could not detect anything yet (he is still investigating this).

I have attached both the engine and vdsm logs

Engine.log:

Can you please provide logs from both ends?
