You can try monit. It's in ports.

try ln -s S /etc/malloc.conf, it might make it easier to trigger.
see malloc(3) for more information.

it wouldn't surprise me in the slightest if it's due to an exploitable bug.

No, OpenBSD does not have anything similar to crashy daemons. ;-)

But if we had (like in ports or so), I'd just set up a cron job.

Well, preferrably I'd just fix the bug, if I were able to track it down. 
Or at least file a bug report to the appropriate people.

Sorry, we don't have crashy daemons here,
you need to go back to linux for that.

hmm, I never had that crashy linux daemon becomes stable when it is
started under OpenBSD.
can you tell me how to enable that feature ?

Guessed enough win.

In addition to Theo's extremely valid point, might not a better question
be, I used to run this crashy daemon on Linux to accomplish task
_.  What does a similar task, but works better on OpenBSD?

Running crappy code on a good OS is still running crappy code.

I don't know about VNC software, but I used to run ssh in foreground
mode over a bad network connection in a script as

while true; do
ssh -Nn -L... host
done 

Of course that doesn't background properly, but that can be fixed if
that is a problem.
