[users at bb.net] Buildbot Hanging

[Pierre Tardy]

Hi Chris. I am not sure exactly what you mean as hang. Could you please
describe me what happens and what should happen instead for you?

I see you are also playing with nextBuild in another thread. Beware that a
crashing or misbehaving nextBuild can easily make buildbot stop creating
new build.
