Apache Crash Problem

I have two servers, both running RHE, Plesk 7.5 This problem I am about to describe happens on both servers, but I have isolated it on one of the servers. Each server has quite a lot of domain on it but this problem also happened when there were only a couple of domains. The problem is: There are several domains where when you enter their address in a browser, the apache process completely hangs up. The only way to restart apache is to stop it, comment out the include line for the vhosts, start the process, re-include the include line, then restart the apache process (graceful does not always work)... Yes, wierd I know. These domains are not running any wierd scripts, all the hardware has been replaced in the box. Truly odd. I can provide several examples (domains), which causes the box to die a death.
