Subject: [EXIM] Hitting hard...
When exim is really loaded, it will start to generate _alot_ of zombies.
It is my secondary mailserver that hits the primary where the inetd has
been down for a day (I running exim from inetd on these).
The load average is moderate:
11:13am up 7 days, 22:47h, 13 users, load average: 0.09, 0.15, 0.15


Here is an process exerpt:

... A total of 230 zombies and 32 real running exim processes.

This is on a Linux GNU/Debian system.
