Have had three servers spontaneously enter maintenance mode. By spontaneous I mean that there was no user activity and maintenance mode was not scheduled.
The UMP displays all three servers as being Active, as in they are NOT in maintenance mode in the UMP, only in the UIM and Admin Console.
The UIM returns a "Error on command (2): maint_until" when we attempt to take them out of maintenance mode manually.
The UIM returns a "Error on command (2): maint_until" when we attempt to set a new maintenance mode entry manually.
1) how do we get these machines OUT of maintenance mode?
2) does requesting maintenance mode issue a write to the SQL database? What would we query and how much would it tell us?
3) Is there any particular network condition which may cause the hub to believe the robots are still in maintenance mode?
