Apache hangs up

You can't run APC with Zend Optimizer. Also, you can't use APC with eAccelerator, but you can use Zend Optimizer with eAccelerator.
 
I had the same problem this morning.
Check in /var/log/messages if you find this:
Aug 10 10:42:44 server kernel: possible SYN flooding on port 80. Sending cookies.

Check if you are not under a DOS attack on your port 80:
netstat -an | grep :80 | sort

Add the IP addresses to your /etc/hosts.deny file.
 
my server also get hangs up! don't why ?

Code:
