My gnu screen is quietly crashing about once per day.

No message from the program or from the system. No detaching message. No system limit message. Nothing. It leaves the child sessions available for reattachment.

How do I debug this? Have others seen this? It doesn’t happen to me on my other (non DO hosts).

Thanks,
-Mike

Hello there,

I would recommend checking your monitoring graphs via your DigitalOcean control panel to make sure that the server has enough recourses.

Also, you can enable the debug mode for the current window of a screen session, by pressing Ctrl+AH (uppercase H, Shift+H if you prefer).

I hope that this helps!
