I ran into this problem after I installed mod-rails on a cent OS server.
To get my changes to take … I kept running
httpd -k graceful
and it kept working until, all of a sudden, it didn’t.
This was the error I got
[XXXX@XXXXXXXXX]# httpd -k graceful
httpd not running, trying to start
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:443
no listening sockets available, shutting down
unable to open logs
Here is what I did. (click to enlarge)
worked like a charm too.
