Sustain switch on glitch?

I think I have a problem with my Mother. Random things will all of the sudden set my sustain switch (on) to an infinite duration. In other words, when you hit a note the note stays on forever. The only thing that clears it is a reboot. This is happening at least twice a session. I try to recreate the problem thinking I can figure it out but I can’t. I then reboot it and move on and then something completely different triggers the problem again,

Has anyone had this problem before? I’m just checking to see if its something I am doing, while I’m still under warranty and possibly get it fixed

The problem was actually midi related. Not the Mother.
