red hat linux scheduler not able to give control to process
===

This is on RHEL 5.x

I have run strace on one of the process that seems to be affected and noticed that the OS didnt give a chance to run for like 12-15 seconds.

The hardware is intel core2-duo-quadcore.

only 8 application processes are running and rest of them all are system processes.

any hints on why this is happening? any config I need to check to tune? This issue happens couple times a day.


All the application processes are I/O bound as receiving a lot of data on the socket.
