HTTPD - Crashing

[cobracrk]

HI, i'm having some problems with apache server, every few hours it crashes for few minutes...

This is the error i get:

httpd starten: [Thu Mar 27 10:21:56 2008] [warn] module php5_module is already loaded, skipping
(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

I'm guessing directadmin is rewriting some of the conf files, but how can i make it not to crash?

Any ideeas?
