Disable commands on "nobody"

Hello,

On a server, I have so many idle apache threads which are useless, using up CPU and eating up RAM.

nobody /usr/local/apache/bin/httpd -DSSL

/usr/local/apache/bin/httpd -DSSL - is running on the user "nobody" and I don't believe anything should really run on this user. If I kill the processes one by one they get recreated with new PIDs. How can I stop this command from being run or any commands being run on the user nobody?

delete the user?

@ Above: "nobody" means no user.

Aren't they threads made when someone visits the site? They should kill them selves every so often.

Its normal that they sit there. It's so that as soon as somebody connects to the server it will assist them immediately. Also you cant disable "nobody".
