Its blowing up here:
if len(known_ids) > 1:
# need a way to handle this intelligently through config
raise ValueError('could not infer dagobah ID, ' + 'multiple available in backend')
And when I comment out this check, it gets the first ID from the list of IDs. And I dont see the jobs which I expect to see.
db.dagobah.find().count() gives 9861
Also, FYI I manually imported about 16jobs by exporting it from sqlite based backend to mongodb backend. Can that be a problem?
Looks like dagobah collection was supposed to be a collection of all the jobs, tasks and hosts. And due to some bug dagobah collection has a bunch of empty dagobah_ids (the job array is empty).
Is there a way to recover all the jobs added in dagobah_job collection?

Is Apache running multiple instances of Dagobah? I'm wondering if some sort of race condition may have got you to this point. With only one instance running at a time, I'm not sure how it would have blown up the DB like that.
Also, is this with stock 0.2 or your custom version? Can you reproduce with 0.2?
Could you also provide some of the docs it's saving to the dagobah collection? Maybe the format of the data in there will provide some clarity.

I dont think apache will run multiple instances of dagobah.
Yes, it is my custom version, I am running it again and I am not able to reproduce it now (yet). It's running from the last 19hours and there is just one entry in dagobah.
The current doc has a lot of entries for jobs, hosts etc and I think this won't help. The jobs which were created yesterday was exactly the same except it had no jobs or hosts.
My understanding was even if dagobah collection is empty, dagobah will recreate it from the dagobah_job and dagobah_host collection. But it looks like dagobah is the primary source of truth.

This is the json. I have removed all the actual jobs and host names.

Never mind. I don't see that problem any more. Will keep an eye on this.
