[Buildbot-devel] Buildbot slave quietly hung after "BuildSlave._commands_unavailable" on master?

[Dustin J. Mitchell]

It looks like the duplicate slave arbitrator is doing the right thing
there, and quickly accepting the new slave connection.  Yet, it
doesn't get any new jobs -- that's unexpected.

Looking through the source, it looks like the arbitrator's
getPerspective deferred is firing appropriately after "keeping new
slave".  That should trigger a call to maybeStartBuildsForSlave(..),
which should start any necessary builds.

Basically, I don't have any good answers for you :(
