I've just noticed that our buildbots connected to the master Buildbot ( http://lab.llvm.org:8011) are not doing much. Even though `buildslave start` is successful, there's no `buildslave` process running.
I've switched them to the staging Buildbot (http://lab.llvm.org:8014) instead and everything seems fine. This makes me think that it's the buildbot master that's a bit unstable. Is anyone else experiencing this?
