Here's the next few minutes of the log files:

<https://gist.github.com/3361963>

It looks like I restarted rabbit around 7:13.  At that point it appeared as
if the shovel had been wedged for about 16 minutes (IIRC there were eight
messages in the 'heartbeat' queue, one is generated roughly every two minutes).

2.8.5 from the debian packages on rabbitmq.com

Erlang should be whatever the latest Ubuntu 11.04 package is.

When I regain access to the sensor I will try this.  Right now I'm
just going through the log files I copied over the last time I was
able to log in (early yesterday).
