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?

Every morning at 7am I get pages from every host I monitor including the display server, that its connection recovered.. the it runs great for the next 23hrs. looking at hobbit web page I see no down time nor do the servers show any down time. But when I click on the historical web link to see the info.. I get this.. I really love hobbit.. but I am not a Web guy at all and I think it might be apache related…
