Linux - killing some processes owned by apache safely

I have a bunch of processes owned by apache that are running for days because they are stuck.

I need to kill them all. And obviously I want to do it safely.

Thus, ideally I should kill them as apache using something like this:

kill 11173 

The problem is that the apache userdoesn't have a shell.

So it seems the only way is escalate to root and kill the process as root. But it is not safely at all (I may kill other processes by mistake).

Has anybody got a better solution?

Thanks, Daniele

sudo -u apache kill 11173

This should belong on http://serverfault.com I guess... but if you want to kill all processes named apache, run killall apache as root. Alternatively, change identity to your apache user with su apache and kill your processes there using kill as you did.
