The problem is, as you can see, with the memory usage. Sorting the
top output by mem usage, I can see that I have lots of httpd
processes each with 20M of mem usage.
Doing a ps auxww | grep httpd | wc
I get 133 processes running.
Everything quite normal. The number of processes has to somewhat
correlate with the number of agents. What you can do:

a) Buy more RAM.

b) Restrict the maximum amount of prefork childs:
<IfModule prefork.c>
  StartServers         10
  MinSpareServers      20
  MaxSpareServers     40
  MaxClients          120
  MaxRequestsPerChild  400
</IfModule>

c) Switch to another MPM, say 'worker':
<IfModule worker.c>
StartServers         2
MaxClients         150
MinSpareThreads     25
MaxSpareThreads     75
ThreadsPerChild     25
MaxRequestsPerChild  0
</IfModule>

d) Disable any module not needed, esp. mod_php4

e) Disable Apache::Reload in apache2-perl-startup.pl

f) Buy more RAM. ;)

g) Switch off mod_perl. Um, Bad idea - better buy more RAM.
