I have Apache/2.0.46 (Red Hat) with server status module installed on my server and I also have a script running which checks every 5 mins whether the apache server is responding to a http request ...

What could be the reason for this could anyone shed some light on this ... Or direct me to some resources which could help me figure it out
2.0.46 is very old and should be upgraded for security reasons if nothing else. The fact that SS is very high on all these requests implies to me that your php scripts are stuck someplace and unable to finish serving requests. Perhaps you have database contention or some other resource that is not available. You may also simply be out of memory, causing apache to thrash (check "top"). If you can't figure out what is causing your php scripts to stick, you can attach to them with a debugger to see where they are at: http://httpd.apache.org/dev/debugging.html#backtrace As a temporary measure, it may also help to reduce MaxClients substantially, which should limit contention on whatever resource is causing the problem.
