I have seen, multiple times, this happen that prevents the machine agent from working:
$ sudo cat /var/log/juju/machine-agent.log 2012-05-07 08:03:44,662: twisted@ERROR: Unhandled error in Deferred: 2012-05-07 08:03:44,662: twisted@ERROR: Unhandled Error Traceback (most recent call last): Failure: txzookeeper.client.ConnectionTimeoutException: could not connect before timeout
I believe it happens if the zookeeper server is slow to respond, perhaps if it has been swapped out or something else.
