After those three mornings would mind commenting those hosts to be certain that reproduces the issue?

Ok.. well it did not do it this morning after adding all of my monitored hosts to the /etc/hosts file... I just cut and copied my bb-hosts file in to my /etc/hosts file, modified in to proper format.. no pages this morning.. so it could have been a dns issue.. if I am clear for three more mornings then I will be satisfied... I will let you know..

Thanks for the heads up. I am very interested in knowing what is the cause and more importantly the solution to your issue, as it may fix mine!
It would VERY nice to be able to print out uptime and availability reports without the dozens of 1 minute outages. I know my issue is related to the box itself (hardware or software) as the issue appears on the hobbit server itself.

Most if not all of my servers are defined by ip anyway, I have a very segmented network so dns is not very helpful across all the different domains and subnets.. i use my hosts file for the most part.. now that I think of it, I wonder if the ones in the host file are still ok? I will let you know...

Can I suggest you use IP addresses for a number of servers and see if they survive through your next episode. That will give you an idea of where the problem might be...
It is the least amount of work towards identifying the cause.

What most people suggest is having a local DNS server, on the Hobbitmon
server itself.
As this is happening at the same time every single day I don't believe
DNS would be the cause of the issue, though it is worth taking a look at
until another idea comes along.

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.
