Is there any known, easy way to reproduce the issue?

Is it possible that something in your boot causes the systemd
configuration to be reloaded?

I now made some changes to git
(9c3349e23b14db27e7ba45f82cf647899c563ea9) that add an explicit
assert() around the line where the devision by zero happens. Most
likely the counting of running jobs got confused, hence I reworked
that code too. Not sure if it fixes the issue, but I can't test this,
since I have no idea how to trigger it...

Anyway, would be good if you could check current git, to see if things
are better for you...
