Several years back, I got involved with a couple of repeaters using the MCC
controllers. They just did strange, unexplainable things. The owners of the
repeaters eventually grew tired of the problems and replaced the controllers
with either S-Com or Link controllers. These repeaters now run with no
controller issues and have done so for a long time.
Not necessarily the "fix" you wanted to hear, but it solved the problems.
