Is it externally visible? (That is, can someone on the internet see it?)
(This helps us know if its maybe an attack of some kind which caused the
problem)
What is the last thing in the log from apache just before it shut down?
IMHO you can ignore the named stuff (but willing to be educated).
When you try to start it, what is in the httpd logs from when it isn't
running till it quits? What is different between THAT sequence and the
sequence in the logs from when it last started ok?
Just a few random thoughts/questions - I am in NO WAY an Apache expert!

Subject: Apache mysteriously stopped and will not start
Hi,
I'm run a web server out of my home office. It is CentOS 6.x with no
real modifications. It is a standard LAMP config. It has been running
since March w/o any issues.
All of a sudden Apache shutdown.
When I run /etc/init.d/httpd start the only response is [FAILED] same
for /etc/init.d/httpd stop
apachectl configtest returns "Syntax OK".
I found these in the /var/lib/httpd/error_log ( read this has to do
with the SSL)

I don't know what to make of this /var/log/messages : ( I read this has
to do with IPv6)

There is a whole bunch of these.
Dig returns what appears to be the correct DNS.
There is lots of disk space.
The last 3 changes I made were 7-10 days ago.
Last change was to run
cd /etc/pki/tls/certs
./make-dummy-cert localhost.crt
I did that because I was trying to configure a new website. I had done
the Apache part weeks before and the site was working. I wanted to add
some email accounts. I'm running Postfix with Dovecot.
So I added the email accounts in the config and when I went to add them
to my Thunderbird, I received an error because the SSL was expired. I
am using a self signed SSL.
A little research brought me to
cd /etc/pki/tls/certs
./make-dummy-cert localhost.crt
However that was 7 - 10 days before Apache just up and stopped.
I am running this server as a learning experience. Someone helped me
with the Bind config and the Postfix/Dovecot config.
I rebooted the server last night in the hopes that something was
corrupted and would be fixed by a reboot. No such luck.
I am at loss for what to look at next.
Thank you very much for all your help!!
