[Buildbot-devel] Calling Stale Broker

[o.rusterholz at bluewin.ch]

Hi everybody,

My Buildbot master and slaves are running on the same windows 
machine. Can't change this at the moment. If this computer is under 
heavy load (from the builds) sometimes some slaves are disconnecting 
and the ones which are running throw a shell exception:

Traceback (most recent call last):
  File "C:\Buildbot_Sandbox\site-packages\buildbot\steps\shell.py", 
line 228, in start
    self.startCommand(cmd)

    d = self.runCommand(cmd) # might raise ConnectionLost
  File "C:\Buildbot_Sandbox\site-

    d = c.run(self, self.remote)

    d = defer.maybeDeferred(self.start)

    _name, args, kw)

line 853, in _sendMessage
    raise DeadReferenceError("Calling Stale Broker")
twisted.spread.pb.DeadReferenceError: Calling Stale Broker

Does anybody know what this means and how I can avoid it? The 
version I'm running is about half way between 0.7.5 and 0.7.6.

Thanks,
Oliver
