[error] (9)Bad file descriptor: apr_socket_accept: (client socket)

Do you still receive above error while stop/start apache manually from command prompt?

There is more possibilities here than could be listed with the little information at hand.

To properly diagnose your issue, we'd really need to know:

1. The amount of memory and traffic on your server
2. The details of your Apache configuration

Per the former, if your server has insufficient resources that would definitely cause a crash condition.

Per the latter, an incorrect configuration, over allocation of resources, or even mis-configured or mismatched modules could also contribute to the server crashing as well.

If I saw your server's configuration, I could probably tell you in a heartbeat what is wrong but with the little bit of
log information you posted above, I really couldn't say exactly what is happening here.

To see the usage of apache processes run following command from SSH:

top -c

See which process is consuming more Apache resource.

WHM > Service Configuration > Apache Configuration, Piped Log Configuration
Is this setting enabled?

No it's not enabled there is empty box where i have to tick it then save to enable it do i have to enable it ? .

Infopro · Apr 27, 2012

Yes, I would. This option has been known to lessen the number of restarts Apache makes processing logs. Multiple topics on these forums, here's one with links to more:
How frequently does Apache restart when managed by cPanel - cPanel Forums

HTH!

HTH!

So how do i know that graceful restarts in Apache are due to log file rotation ?! what if it's not because of log file rotation ?

I cannot answer "what if's", my apologies. I can link you to a search of these forums for a specific snip of your log message though. It may be helpful to you:

site:forums.cpanel.net "seg fault or similar nasty error detected in the parent process"

Thanks for your help , Does enabling Piped Log cause changes to my httpd.conf or a full rebuild ? because i have a special configuration
