The only time I have found excessive memory consumption with apache was
when I tried to use ldap authentication on apache 2.0. The memory usage
would creep up over a period of time, and eventually I had to restart
apache (every few days, or so, I think). I gave up on ldap and the
problem went away.

I have since used ldap authentication with apache 2.2, and there are no
problems there.

I agree - apache should normally not need to be rebooted for months at a

Sounds like my ldap problem with 2.0, see above...
