There's a lot of things it could be. I'd check your Apache logs and see if any error messages are coming up.

My best guess is that your MaxClients is set too low in Apache. Search httpd.conf and look for "MaxClients". It seems you're probably running 100+ httpd processes at the time when you're having problems accessing it, so the MaxClients should probably be set to at least 200. The default is usually 150.

MaxClients value was set to 1024.
there is usually 250 runing processes.
memory, cpu all loading are nice.
