MaxClients
Is there a "rule of thumb" way to determine the appropriate MaxClients
setting for my servers?
Also, if I set my MaxClients to let's say 300, is there a way for Apache
to e-mail me to let me know when I have exceeded 250 on that server? Or
is there a better way to do this?

That's actually my fault. I should have been more precise. The module is
called mod_status:

Joshua,
Thanks. But that brings up a newbie question <embarrassing grin>. What
do you mean by "the server-status module"? You referring to 'httpd
status' or something else?
Also thanks for the heads up about the mod_ssl user group earlier.

If the machine is used only as a web server, you should set MaxClients to
the highest value that does not cause memory usage to exceed the available
RAM (ie, make sure the machine isn't thrashing). Although some
calculations may help you determine a ballpark, you will probably need to
monitor the active server for a while to find actual memory usage.

Nope. Apache doesn't send email. I think there are snmp modules
available (from covalent?), or you can use the server-status module to
check up on the server.
