I switched one of our workers to the main Buildbot and everything seems fine #fingers-crossed. I guess that that was a temporary glitch?

We haven't updated our local Buildbot installations - still on 0.8.5. Should we update?

Hi Paula,

This error is fine. The buildbot has tested the worker version. 0.8.x apparently does not have that method. The error gets handled gracefully on the server side. At least it seems so so far.

That should not prevent your bot from connecting.

Thanks

    Hey Andrzej,

    What are you seeing in your buildbot logs? Is it this error?
    `twisted.spread.flavors.NoSuchMethod: No such method:
    remote_getWorkerInfo`

    If so, you might want to try updating your buildbot worker.
    I updated llvmlibc's to 2.8.4 and that seemed to solve the connection
    problem:
