I assumed a DLQ was available.

Richard,
Applications sharing the same channel will also share the fate of that
channel. If one application causes the channel to fail, by putting a
message to a non-existent queue when there IS NOT a Dead Letter Queue then
the channel will end. With the channel down messages for all applications
using that channel will stop because they will just sit on the transmission
queue. It is for this reason that we recommend people do have Dead Letter
Queues.
Cheers,
P.
