So on all the other systems that this is deployed on it is started automatically at boot and it's controlled with service or systemctl. On this system because I do not have remote access and I do not have a very competent set of hands over there it was never set up to run as a service. So a user manually starts it by running the daemon script. This had been running on the machine like that for 8 months. The nightly crash just started on April 21 and has happened every day since. > If it is dying, are you logged in when its running? I am not 100% sure, but I think the user sus, starts the daemon process and then exits the su. > does it require you to be connected when its running? No. The underlying script polls dirs looking for files, and loads data into a db. > Maybe you should run it in a > screen/tmux instead of daemonizing, so you can see stderr/stdout? stdout and stderr are written to a file and when the daemon gets killed or dies or whatever happens to it, the output in the file abruptly stops, just like what I showed in the messages file.
