I moved a guest between servers over the weekend and when I attempted to start it I received the following error:
Starting httpd: (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
I checked its etc/hosts and that did not have the loopback address in it. I even tried binding the IP address on Listen in httpd.conf.
There are two other guests on the server that run an Apache instance and NGINX as-well. I shut both of them down and then the moved guest could happily start Apache. If I shut everything down and started the NGINX guest first followed by the existing Apache instance both work fine.
Any thoughts as to why this moved guest cannot start Apache ? It is though something is completely glomming port 80 :(
