Can you do a dd if=/dev/sda of=/dev/null from the disk in which the stuff is
stored? If it is so random I'm curious to see if the fs is having
problems. I have my money on a bug in the software or bad
disk/fs/controller.

I don't know how many hosts are affected, percentage wise, but it's
definitely not every host. And for the hosts having the problem, it's not
even the same graphs that are having the problem.

Not sure if you mentioned this or not but does that weird value show up
in all RRD graphs or just a few hosts?

Do they monitor the same devices? I think there has to be some
similarity between the two as they had the same problem at the same time
(though this isn't 100%, it's logically the first place to look). Hardware
isn't of much concern here as they don't communicate and the chances of both
servers going bad on the same date is simply astronomical.
Are there any kind of auto updating services running on them?

We only have two Hobbit servers, and it is affecting both machines.
No, these two Hobbit machines do _not_ communicate with each other in any
way.

Is this problem not showing up on another Hobbit server? Do the
two Hobbit servers with this problem communicate at all (share data/SNMP
traffic/etc)?

That's the thing, there aren't any similarities between these
two machines. They are different hardware, different OS, different network
segment, and different hosts being monitored.
There were some recent changes in the past month to one of the
hobbit servers, with a bunch of custom RRD graphs added. But this wasn't
done on the other hobbit server. The only thing changed on the other hobbit
server is more html web checks added; nothing out of the ordinary.
