+Subject: [PATCH 1/1] rabbit: redeclare consumers when ack/requeue fail
+
+In case the acknowledgement or requeue of a message fail,
+the kombu transport can be disconnected
+
+In this case, we must redeclare our consumers.
+
+This changes fixes that.
+
+This have no tests because the kombu memory transport we use in our tests
+cannot be in disconnected state.
+
+Closes-bug: #1448650
