[imp] size of server processes...

[Liam Hoekenga]

We think we may have figured this out (at least for Solaris).  My thanks to my 
coworker Johanna Craig.

Our symptoms..
- low load
- almost no swap free
- huge httpds (most 50mb+, some taking more than 140mb of memory)

Our webservers get HUPed at midnight so we can rotate logs.  After restart, the 
apache processes are ~ 20mb, but they grew slowly throughout the day.

Our MaxRequestsPerChild was set to 0 (unlimited), but we've put it back at 100 
(the default).  We think that we're running into a memory leak someplace (php?) 
in long lived apache processes.  Now that they die and get respawned, our 
machines seem to be happier (and httpd takes up about 30mb per process).

btw - switching to SMTP did seem to help our delivery problems.  We've got one 
machine set back to delivering stuff via sendmail (to see if the change in 
MaxRequestsPerChild have helped).
