      Description

      After performing an upgrade from 4.3.2 to 4.4.2 I am no longer able to Cancel Maintenance mode. The GUI shows the following error a few seconds after pressing the button:

      Command failed due to Internal Server Error

      The management server shows the following error:

      There is absolutely nothing in the agent logs even if I use the DEBUG logging.

      I get the same error if I use CloudMonkey to cancel the Maintenance mode.

      The database shows resource_state as Maintenance. There are no running vms on the host.

      I can manually update the db resource_state to Enable and perform agent restart. After that the host is once again out of Maintenance mode and usable. If I do the Maintenance mode once again, I am unable to Cancel Maintenance mode.

      I am running Ubuntu 14.04 on both the management server and the host agents.
