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

[Lior Vernia]

If I'm not mistaken, heartbeat intervals are configured to 10 seconds by
default.

The command times out queries for the status of VMs on a host - any
reason to suspect why that's taking long? Does it happen on specific hosts?
