| Eoghan Glynn | 2013-12-09 16:06:40 UTC | Doc Text | Cause: a defect in the QPID topic consumer (re-)connection logic under the v2 topology caused a duplicate of each RPC notification being delivered to every subscribed consumer. Consequence: samples derived from RPC notifications were duplicated to the extent that the collector service makes multiple subscriptions to the topic control exchanges for the individual services (e.g. nova). Fix: a single queue is created for each topic, to be shared among all consumers of that topic, resulting in each RPC notification being received by only a single consumer, Result: the prior duplication of samples derived from notifications no longer occurs. | |

Fix: a single queue is created for each topic, to be shared among all consumers of that topic, resulting in each RPC notification being received by only a single consumer, Result: the prior duplication of samples derived from notifications no longer occurs. | A bug in the QPID topic consumer re-connection logic (under the v2 topology) incorrectly resulted in the creation of duplicate RPC notifications delivered to every subscribed consumer. As a result, samples derived from RPC notifications were duplicated to the extent that the collector service made multiple subscriptions to the topic control exchanges for individual services (e.g. nova). With this release, QPID now creates a single queue for each topic, to be shared among all consumers of that topic. This ensures that each RPC notification is only received by a single consumer, preventing any unnecessary duplication of samples. |
