ACP completely disappears randomly

[Paul Kent]

Hi All,

Over the past few weeks, we have encountered several instances of a Scheduler Stopped Working error. Sometimes it happens on startup, and then we get a message saying operator intervention required, last night it ran 2 one hour plans and then stopped, and then failed. I had a quick look and maybe there is an issue when it comes to shutting down the observatory if scheduler thinks there is nothing to image for a while?

I will post two logs from last night. The first is the failure after a sequence of images, the second is what happend 3 hours later when I noticed the issue and tried to restart scheduler.

Thanks

Paul Kent
