apache 2.0.63 and php5

[xer]

Hello any1
Strange, i have a apache web 2.0.63 and php5 on a 6.4-STABLE, but every time 
i reboot the server, the php pages does not work at all, especially some 
self tools made with sh scripts and sudo (tail cat and some php buttons), 
refresh of the page does not solve the matter..

For fix it, i need to make a simple apachectl stop and start, then the php 
pages start to works...

the logs did tell anything...

any ideas?

appreciate your help
TIA
