in my experience, seems it is easier to trigger when the system is under heavy cpu load. and as a bad workaround, i just put a "sleep 1" in between the 2 calls.

there can be race when starting it in background and immediately issuing a command to session.

$ screen -S foo -dm
screen -S foo -X stuff "/path/to/script.sh^M"

No screen session found.


easier to reproduce if screen was not run previously or was flushed out of memory (/proc/sys/vm/drop_caches)
