This rarely happens but when it does it blocks everything in the scheduler.
I generally have 10 - 30 objects in the scheduler (variable stars) and I have a couple of times noticed a slew that never completes.
I'm not sure if its KSTARS or INDI or the mount firmware

My mount is a CEM120.

Attached is a screenshot showing what I see in the EKOS analyse tab looking at last nights run. It started a slew at 2:43am and this never finished until 4:54am when the shutdown procedure kicked in and parked the mount and closed the roof.

I'm just wondering if anyone else ever experienced this? I'm only started noticing this maybe 6mths ago. Its rare but its a pain.
