We need to check engine logs but I suspect that this is just a duplicate of 1350718 which was closed as a duplicate of 1350763. 1350763 is ON_QA
Can you please provide logs from the failing host and from the engine? You can use rhevm-log-collector or sos to collect them.
Sorry, we need engine.log from the engine VM since the issue is probably in the engine.
Please reopen if you hit this again and engine logs are available
