Ok, first off my apache tends to stop working. i get an error message and it closes every once in a while.. but i notice it tends to happen when im working on my site and i click the refresh button in firefox(but only on my site pages, not other sites IE:google)

also i noticed when someone registers on my site, it works and its in the DB but i have to restart the server in order for them to be able to get on. is there a way to fix this??
