I have a 3 axis stabilized gimbal that is attatched to a ceiling. For some reason, if I dont touch anything in 20-30 minutes gimbal starts to move erratically and fast, spins in all directions and only a system restart helps that situation. Itries to connect to a camera once while that was happening and found that for some reason a "Read errors" started to accumulate for a Roll encoder installed on that gimball. Full log is at the bottom of that message. The question is: why might that be happening and how to prevent it.
