Description of problem:
In this particular case, it is RestoreAllSnapshotCommand that is not polled.
VM: didi-rhel6-engine (9beb6974-d078-41da-a9bb-7abec821e9d1)
Command: RestoreAllSnapshotsCommand (2016-09-07 15:25:22,129 (default task-253) [27207670]).


Version-Release number of selected component (if applicable):
4.0.3

How reproducible:
Rarely

Steps to Reproduce:
Not clear

Actual results:
The 'execute' phase of the commands ends successfully, task is being created, but the command doesn't end in several hours.
Only after restarting the engine (~2016-09-07 20:57:51,063), the command is being ended (2016-09-07 20:58:58,004).

Expected results:
The command should be polled properly and end in a reasonable time.

Additional info:
This is not the first time we faced this issue on rhev.tlv.
This time we checked the command_entities table and it contained 33 entries at ~16:30.
Comment 1 Red Hat Bugzilla Rules Engine 2016-09-08 07:44:01 UTC 
Bug tickets must have version flags set prior to targeting them to a release. Please ask maintainer to set the correct version flags and only then set the target milestone.

ok, ovirt-engine-backend-4.0.6-0.1.el7ev.noarch
