I have a vps running my websites. I configured my websites to use fastcgi so in proccesses I see:
28696 mywebsite 20 0 152m 12m 6460 S 0 2.5 0:00.31 php5-cgi
this is normal. but I also see lot of following prccess eat RAM:
28522 www-data 20 0 241m 21m 3108 D 4 4.2 0:00.07 apache2
but I have not configured any website to use (run as) apache2 module and under www-data user group.
where these proccesses came from?
