Just to be clear: if my maintenance script encounters an unexpected
error or situation it can't deal with it exits immediately right after
emailing me a diagnostic and printing a big red "ERROR" on the screen.
The script won't then run again until after the issue has been diagnosed
and resolved (because it requires a manual restart). The code that
manages this process is free software written by your's truly:
So as long as my maintenance script is still running and there's no big
red "ERROR" on the screen then things are probably okay and it's
probably processing whatever it says it is without issue. I do generally
go weeks at a time without issue, but the process does need to be
manually restarted if the server reboots (e.g. during APT maintenance)
or if it exits due to error.
May the Force be with you,
