Problems with Apache2 starting up

[Jeff Stubbs]

Greetings,

I've used MP to build an Apache2/MySQL/PHP5 server for spouse's  
employer last November. Since startup then, everything has worked  
fine. However, late yesterday afternoon, I got a call that the sites  
weren't accessible. Since I was a work, I told them just to restart  
the machine. Machine restarted fine, but Apache2 didn't start up on  
boot. SSH'd in and ran 'top', no httpd processes were running.  
Launchctl showed that the plist file was already loaded. Using the  
apachectl command (MP's, not Apples), the server started up. Just for  
kicks, this evening I restarted the machine, Apache2 wasn't heard  
from, but will start from the command line. Anyone one experiencing  
the same problem?

Machine Data: dual 1.8 Ghz G5, OS X.5.5,
MacPorts 1.700, Apache 2.2.10, MySQL 5.0.67, PHP 5.2..6

Some of the installed ports are now slightly out of date, but  
shouldn't suddenly cause problems. Two Daemondo processes are running  
after starting apache. I usually scan the user & dev lists, but don't  
recall anyone reporting a similar problem.

Thanks,

Jeff
