I saw on a terminal on the ops workstation that someone had logged into h1fescript0 and started the query grace db script without running it in screen. I ctrl-c terminated that script. I did a listing of the current screen sessions (screen -ls) and saw two running. The one with PID 4403 had the printout from a crashed query db script. I restarted it in that screen and detached from the session. It is now running in screen with PID 4403.
