Any progress on figuring out what's going on here?

Hm, it seems that it has been happening since the fedmsg-hub service was restarted. I restarted it again and depcheck was scheduled since then. Will be keeping an eye on it and close the ticket if it's indeed fixed.

OK, seems to be fixed. Not sure what caused the issue though. :/

Now depcheck and upgradepath don't run on production, for the last 2 days.

It's scheduling depcheck/upgradepath again but I'm really not sure what happened. The biggest thing out of the ordinary this week was a problem with yahoo's bot beating up the production buildmaster but the timing doesn't match up and I can't fathom how the two could be related.

We'll just have to keep an eye on it, I guess :-/
