Why is Apache running so many processes? Excessive RAM here?

[mron]

I notice Apache is running multiple processes on my Debian 7 server. It seems like www-data is running apache2 more than it should (using too much memory too), please, help me.

Code: Select all

Owner     PID       Size        Command  
root      5186   357052 /usr/sbin/apache2 -k start
www-data  5188   154352 /usr/sbin/apache2 -k start
www-data  5190   361448 /usr/sbin/apache2 -k start
www-data  5191   362572 /usr/sbin/apache2 -k start
www-data  5192   362636 /usr/sbin/apache2 -k start
www-data  5193   363812 /usr/sbin/apache2 -k start
www-data  5194   362348 /usr/sbin/apache2 -k start
www-data  5195   360416 /usr/sbin/apache2 -k start
www-data  5196   363752 /usr/sbin/apache2 -k start
user11    5197   362160 /usr/sbin/apache2 -k start
www-data  9548   361240 /usr/sbin/apache2 -k start
www-data  9848   362220 /usr/sbin/apache2 -k start
