I am facing a problem with Apache on CentOS 6
Apache 2.2.19 is complied from source.
I see so many reading requests in Apache status page, as per my previous experience this "reading request" issue mainly comes when any of the internet route having any problem and it request takes time to completely reach to Apache, but this time there is no network issue.
I have ran same setup on CentOS 5 it works well, but on CentOS 6 it show 60%+ reading requests, web site has 20-25 requests per second that becomes 80+
I also tried to upgrade Apache to 2.2.24 but it is same on new version as well.
Anyone else has experienced this issue?
I'd recommend you to sort out the connections. Find out if they are coming from the same client or the same subnet of the clients. Doing a simple tcpdump capture to analyze the data seeing if it's a good R or a bad R.
Don't really think it's because of the version.

I have already checked but all requests are from different IP's and even different subnet When there are less requests it works ok even if there are more than 60% reading requests but during peak time when concurrent requests goes beyond 150, due to reading requests it becomes 300+ requests processing at the same time and that then Apache stop responding as maxclient is set to 300. CPU load also goes up and thing become very slow.

Did you check mpm settings of httpd-mpm.conf ?
default response client value for 2.2... versions is 150 and 2 proccessor for simultaneously response ....
applying httpd-mpm.conf in httpd.conf and changing mpm thread settings will help you...
