If 'openbsd-inetd restart' fixes it then the problem is that inetd has
died not qpopper, right?
[An opportunity to advocate using 'service' instead. It cleans the
environment which prevents some userspace environment polution
problems from causing trouble. It is just a good idea.]
man service
service openbsd-inetd restart

I know you already solved your problem. But... This is a very simple
brute force hack.
$ service openbsd-inetd status
inetd is running.
Therefore create a script that runs this check as often as you like.
When it turns up that it isn't running then restart it. If this is
run by cron then the output of the restart will be mailed to root as
nofication of the action taken.
#!/bin/sh
if ! service openbsd-inetd status | grep -q 'is running'; then
service openbsd-inetd restart
fi
exit 0
In the if statement there I would be inclined to dump out any
information I would need for debugging why inetd died. I have never
seen that be a problem. I have been using it for literally decades
and it is rock solid. If it dies then I think something must be
actively killing it. I would definitely try to debug what is
happening there.
