> Key: QPID-5513
> URL: https://issues.apache.org/jira/browse/QPID-5513
> Project: Qpid
> Issue Type: Bug
> Components: C++ Clustering
> Affects Versions: 0.25
> Reporter: Alan Conway
> Assignee: Alan Conway
> Fix For: 0.27
>
>
> HA uses a single link and a session per queue to replicate queue data. That
> means the number of replicated queues is limited by the number of channels,
> which is 32k in current Qpid.
> To reproduce:
> - create a 2 node cluster.
> - declare 32769 queues
> Actual Result:
> - no error observed by the client declaring the queues or in the primary log.
> - backup broker exits with a critical error saying "not enough channels"
> In the short term it is not straightforward to remove the limit, however the
> error reporting needs to be fixed:
> Desired result:
> - client declaring the queues receives a "resource-limit-exceeded" exception
> with appropriate message.
> - primary logs an error indicating we exceeded the replicated queue limit
> - primary and backup broker continue to function normally.
