_If_ it got killed. But it did not. Take a look at that snippet from top, it
was RUNNING and eating 100% CPU. This was AFTER sending several SIGKILLs to
it. The only thing that helped was rebooting the machine.
Additional note: I checked my system stats to find out that 100% of CPU used
was used in kernel space. So I guess it might be kernel bug as well.

Becoming an unkillable CPU eater is not a bug? I certainly not think so!

For reference, it was not invoked from cron job, it was invoked from
debian-policy's postinst script. So it's not specific to dwww's cronjob.

Yeah, this eats a lot of resources, but I can kill it.

I'm afraid the problem here is not that it eats a lot of CPU cycles, but that
one cannot kill it. This has nothing to do with different usage contexts and
don't think different configuration will help.
Kind regards,
