I wrote a script called uptime_guard.sh (no Perl at all :( ) which is used to watch disk space, database segments, processes, etc. etc.

After six months we discovered that it, sometimes on some machines, crashed after being run for a measly three, four weeks. So I also made the script create another guard process, watching uptime_guard.sh . So who watches the watcher(1)?

Custos Custodio.

I think things like that is important.

(1) That would be "Quis ipsos custos custodes?" in Latin.
