It appears that you’re receiving an “Address already in use” error.
You may want to run “service apache2 stop”, and then afterwards, review the running processes to see if there is a stuck “apache2” process in the list.
If you see any, kill it off with the command “kill -9 XXX”, where XXX is the process ID of the apache2 process you’re looking to stop.
