Re: runit not collecting zombies

[Radek Podgorny <radek@podgorny.cz>]

Yeah, the PPID of the zombies is 1 for sure.

Actually, I'm not experiencing it with lighttpd (I've just found a
similar problem on the web with better explanation in hope it helps).

There are basically two types of zombies on my system. Lots of sshd
zombies (I don't know where they come from, maybe automated login
attempts...) and lots of arp zombies. ARP does not for at all AFAIK.
It's there because I have a python script which executes arp and run
that script from cron.
