Your Debian Sarge’s web serving has gone weird on you. You restart processes, trouble prevails. Then try this.
sudo netstat -tlnp
What you’d need to get the apache2 process id, to sudo kill -9 <your process ID here> it. A few times…
When all are dead, restart. “It’s a Sarge thing.”
why not to try #killall apache2 instead ? ;-)
There are 2 rections to this tip: a) Excellent! b) I suck.
