apache won’t start after latest system update

Not sure if this is a coincidence or not, but after the latest mac system update, I was no longer able to start Apache.  All I kept getting was the following error message in my apache error logs:

[alert] (EAI 8)nodename nor servname provided, or not known: mod_unique_id: unable to find IPv4 address of "[myservername]"

I tried rebooting and stopping/starting MAMP several times, but it always came back to that error and wouldn’t start Apache.

Finally I ran across this post that led me to the right answer:

I’d suggest adding your hostname to /etc/hosts. Something like “ testbsd” should help.

It worked like a charm.  After I added my server name to the hosts file, I could restart Apache just fine.

Thank you forum posters ;)
