Sometimes I notice the server is running slowly and at those times a ps -e shows that logger and tee are running but I can't think of why. Is this a known issue? Why would these need to run without being called? When this happens there are very few systems running, but there is some connection to running Chromium maybe but I am not sure.


Use pstree -s <PID> to find out what a process's parents are.

For example:

$ pstree -ps 1518

If the process was started by a running service, then systemctl status <PID> will show the corresponding service.

$ systemctl status 1523
