Doesn't seem so to me.

Did you attach the last one? Could not find it.

In vdsm.log I see:

stats will be missing. (momIF:79)

It seems to me like vdsm tries to connect to mom and fails.

If this still happens, I suggest to:
1. Move host to maintenance
2. Restart both vdsm daemons and mom
3. If it still happens, check/share all logs to find out why it fails.

Best,
