Alan Conway created QPID-5513:
---------------------------------
Summary: HA backup fails if number of replicated queues exceeds
number of channels.
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
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.
