Hmmm... bummer, there goes that theory... If you are using IP addresses, and
you are still getting failures on these hosts, then dns is not involved. A
ttl of five minutes is fairly worthless for a caching server. It only helps
if it hits the same device within five minutes, as hobbit is pinging every
five mins (default), you will most likely always be pulling from your
master/slaves...

Well almost (good 99%) of my hosts have the testip tag, so it doesn't
need to look up the names. The things it does look up are 5m TTLs
though.

What is ttl set to for your domain? It would be interesting to see if the
issue reduces with a higher ttl. Another way to ensure this is not the
area
of the issue would be to set the dns server up as a slave.

That was someone's theory in a very large post about this issue in the
past. I did install a caching only named on the box and it did not
fix the problem.
Did relieve the stress of my other DNS server though :)

Hi Josh,
This doesn't relate to the apache error, it relates to your problem...
This
is a theory...
I am wondering if you are running a caching name server on your hobbit
installation? If not, I am wondering if the fping places too high a
load
on
your dns server and misses the occassional host. Even with a caching
dns
server you may see the issue every time ttl expires.

Gavin,
I am having a very similar issue - though it is not every single day.
My
issue is that every host (or almost all of the hosts) will have
conn:red
and
then come back up ~60s later. I just confirmed this weekend that it
is
not
related the Via NIC (Using an Intel Pro/100 S now).
An issue like that is almost always Apache related. Can you post the
errors in /var/log/httpd/error_log from this time period?
