I can see that my server load increases to more than 200-300 range. Before 1 week the maximum load was around 20-25. In top and ps -ef i can see a lot of httpd threads and the PPID of most of the httpd request are of the same PID. When i verified this the parent process ID is of root. Please let me know how i can reduce the server load. I have searched a lot for this but not able to find out a proper solution for this. Please let me know.

Please see below a part of the top output.
