Actually, it might be simpler than that... :/

Long story short, there's a $XYMONRUNDIR patched in pointing to
(/var/run/xymon/) to differentiate certain daemon-controlled files for
SELinux purposes. Sockets and pid files are fine there, but checkpoint
files shouldn't be if they're expected to survive a reboot/crash (which
they are). xymond state will be recreated relatively soon, but the alert
checkpoint is gone and would be missed. Kind of surprised I hadn't caught
this, or it hadn't been reported by now...

Quick fix: Double check the --checkpoint-file and --restart options for
[xymond] and [alert] in /etc/xymon/tasks.cfg -- change them to point to
$XYMONTMP (default: /var/lib/xymon/tmp/ in the RPM) instead of

This is almost certainly a packaging issue; I'll post a note on this on
the site and get a new RPM out soon.
