Apache won't start after successful upgrade to 4.2.23

I'm trying to figure out why is apache trying to bind a socket to 0.0.0.0.0 but have no clue, i'm looking at configurations files from addons, httpd.conf....

ok i've added ServerName 127.0.0.1 at the end of http.conf to suppress the message
apache-ssl: Could not reliably determine the server's fully qualified domain name, using 192.168.2.200 for ServerName

I've put # in front of the line Include /etc/frontview/apache/Virtual.conf to suppress all virtual domains
i've put # in front of the line Include /etc/frontview/apache/addons/*.conf to prevent addons from loading

but i still get the error

httpd not running, trying to start
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

i think it is a system related error, other process bind socket and there is a conflict...

does anybody know how i can list which process uses which port ?

To identify the process using the port i ran command

netstat -lnp | grep '0.0.0.0:80'

but i get not output...

Any clue anyone ?

I killed all the proccesses returned by the command

netstat -tulpn

i checked nothing was mapped to sockets...

when i try to start apache i have the same error... :oops:

i forced usage of ipv4 instead of ipv6 by changing

Listen 80
Listen 443

to

Listen 0.0.0.0:80
Listen 0.0.0.0:443

but still getting the same error

Have you tried stopping your add-ons one by one to see if any of them are the problem?

Hummm no i didn't try to kill addons one by one, i thought that forbidding their loads within the httpd.conf was enough...

ok i'm gonna try this thanks a lot for your help... i appreciate a lot !

stopped all addons manually... between each stop tried to start apache, still the same error...

i'm lost : (

If there are any addons you no longer need execute the remove script in /etc/frontview/addons

Perhaps also try Re-installing other add-ons you wish to keep and check you have an up to date version installed.

Revert your apache config back to what it was before.

What files are in /etc/frontview/apache/addons ?
