------------------------------------
Summary: HA backups continuously disconnect / re-sync after
attempting to replicate a deleted queue
Key: QPID-4285
URL: https://issues.apache.org/jira/browse/QPID-4285
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: 0.18
Reporter: Jason Dillaman
Running qmf-stat on the primary broker shows that auto-delete queue XYZ exists,
but running drain against the queue indicates that the queue does not really
exist. QMF is out-of-sync with the true state of the queue and as a result,
the deleted queue was replicated to the backup broker. When the backup
attempted to subscribe to the queue, it received an error that the queue was
deleted which results in the backup disconnecting/reconnecting to the primary
and re-attempting the state replication.
Sample log output from backup:
