In our ovirt environment(oVirt 3.4.4), we have 2 hosts, and the spm changes hourly between the 2 hosts. In the events of DataCenters there is following message each hour:

'Data Center is being initialized, please wait for initialization to complete'

In the vdsm.log i found following error message:

Thread-13::ERROR::2015-06-23 13:38:36,667::task::866::TaskManager.Task::(_setError) Task=`e450d7d6-771d-4c51-90b7-c6b10da37897`::Unexpected error

The attachment is vdsm.log and engine.log. The error occured at 2015-06-23 13:38 and 2015-06-23 15:38 in vdsm.log.

(by the way, in the other host the error occured at 2015-06-23 12:38 and 2015-06-23 14:38)

And in the engine.log i found following error message:
