Sorry. Then I'm unable to reproduce this on the current Debian package.
Can you check this version?
> This is not the case, monit is not trying to restart the service, it
is entering a tight loop trying to read the PID file, as I stated.
Here is my steps to check this:
1) install Sid's version of the package
2) install openntpd + edit /etc/init.d/openntpd to exclude -p option
3) manually create (touch on start) and remove (on stop) empty pid file in
/etc/init.d/openntpd
4) include /etc/monit/monitrc.d/openntpd in /etc/monit/monitrc
5) restart openntpd
6) restart monit
After the last step:
$ cat /var/log/monit.log

Yes, I see a lot of spam, but it works well for me.
> Monit should fail gracefully, handling an empty PID file the same way
it would handle a non-existent PID file.
That's very different situations, imho.
