Icinga notified us of the presence of a
/var/run/reboot-required file on various servers. i.e. we were getting a
SERVICE STATUS: CRITICAL file or directory /var/run/reboot-required exists message in Icinga.
We duly did a reboot only to find a couple of days later the message had cropped up again.
I don't recall having to reboot servers so often. I'm starting to think these are just spurious messages and we should simply ignore them.
Is there any harm in that?
