Advant Master - Object is Locked by Another User
To resolve the problem the first time we rebooted both of the connectivity servers. The second time the problem occurred the customer rebooted only one of the RTA boards and the problem immediately cleared.
I am aware that there is a known issue if objects are imported from another system and have the wrong network number configured in the control connection aspect. This does not seem to be the case here. Are there any other known issues and/or solutions for object locking problems in 800xA for Advant Master ?

It has been issues with object lock with older firmware versions of controllers i.e MP200/1 and older AC450
An upgrade to latest AC450 version is one way to reduce the problem, it may happened if you have a bad network or shut down the CS server incorrect.
Was the selected flag = 1 in the controller when you had a problem to select th object from a face plate ?
Normally the lock in the controller, (selected flag) is released after 5 minutes in the controller in nobody touch the object
If an operation is performed on the object during the lock period a new 5 minutes lock period will be started.
Then close and re open the face plate
