So far I only have 2 days of logs to look at but it’s not run more than 18 seconds at a time.
I love your use of the timeout command. I’m going to look into that. However right now my primary concern is not killing the process but making sure another one does not start up. Since this is doing DB work, I want it to finish.
Can’t say that I’ve ever seen it go 20 hours! 
Cheers!
