Five seconds earlier there was an error:
=ERROR REPORT==== 6-Dec-2011::10:16:15 ===
connection <0.20.170>, channel 1 - error:
{amqp_error,precondition_failed,"unknown delivery tag 2",'basic.ack'}

It didn't look like that has caused the application to fail, but are you 
saying it is probably related?

It's not entirely clear what that error means to me either, other than 
that there was a problem with an ack somewhere. (Which I'll try and 
track down now)

Is there a way to decode these error reports?
As someone who isn't familiar with Erlang, nor the internal source code 
of RMQ, these errors are quite daunting.

Thanks again for your help,
Toby
