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,
