In our hobbitd.log we have several messages stating: "Hostname '<various>' in tree, but no hostinfo."
This is in a migration from bb to hobbit, and all 22 hosts mentioned are no longer in the bb-hosts file. I have used 'bb 127.0.0.1 "drop <hostname>"' in an attempt to get rid of it, but no success. So our hobbitd column sits at yellow.
Has anyone seen this problem before? My search of the mailing list only revealed one message with it that was seemingly never answered (probably because the gentleman slipped the question into another unrelated thread).

Are they listed in the ghosts report? If so, the client code is still reporting to the server.

I checked just in case, but as I suspected, no. We have never had clients on these machines. Several of these machines also don't physically exist anymore, and their IPs have not been reused yet.

Just found the problem. We had mrtg polling these machines. I imagine hobbit didn't know what to do with the data. I took out the hosts in the mrtg.cfg and redid the 'bb 127.0.0.1 "drop hostname"' and that got rid of the messages.
For anyone doing a search on the message, it seems (to me) to mean that hobbit got some info it doesn't know exactly where to send off.
For anyone's reference, we use the bbmrtg.pl script to integrate mrtg with hobbit, not the built in integration.
Hope this helps someone else. And thanks for the reply Rich. You sent me on a path that led to the solution, even if indirectly. =c)

I see you've found a solution to the problem.
This is one of those "this is impossible but let's check just in case" things that programmers check because they do happen anyway. The error is logged when hobbitd responds to a status query, typically when the web pages are updated with the current status of all the hosts.
Hobbit has one data structure holding all of the test-results that have been reported, and another data structure holding the list of hosts it knows about (basically, it's the contents of the bb-hosts file). Obviously, a status cannot refer to a host that isn't in the bb-hosts file; status messages from unknown hosts are ignored (they only show up in the "ghost" list), and if a host is removed from bb-hosts then it should be detected at the time the bb-hosts file is reloaded, and any status messages should then be purged - and they should definitely disappear after you do a "drop" on the host.
So this is a symptom of an inconsistency in the data Hobbit has in memory.
I know there is a bug in the way hosts are dropped from the internal tree, and this could well be an effect of this bug. So it is probably wise to stop Hobbit and restart it - this bug has the potential to cause hobbitd to go into a state where it just spins using 100% cpu time. Restarting Hobbit will clean up the inconsistent data it has in memory.
