I dont know if it has to do with the zombie code, but i have it running on
two of my exim boxes currently, 4.30.1 and both show the same behaviour. I
have 10 mailscanner children normally, but they just die after some time
and wont come back. Its all running ok, for hours, but then they drop out
and i have to restart mailscanner to get it going again. Noticed this on
my 2nd box, and seeing this on my 1st one also now.

I also see this in /var/log/messages:

to SIG_IGN but calls wait().

Its really weird, it seems like its slowely dying...
