-------------------------------------
Summary: [Broker-J] BrokerLoggerStatusListener produces repeated
stacktraces
Key: QPID-8694
URL: https://issues.apache.org/jira/browse/QPID-8694
Project: Qpid
Issue Type: Improvement
Components: Broker-J
Affects Versions: qpid-java-broker-9.2.1
Reporter: Daniil Kirilyuk
Fix For: qpid-java-broker-10.0.0
When an exception happens in logger itself, it is handled by
BrokerLoggerStatusListener, leading in some cases to repeated messages, e.g.:
{noformat}
2025-04-02T10:35:42,245Z ERROR [AsyncAppender-Worker-graylog]
(o.a.q.s.l.l.BrokerLoggerStatusListener) - Unexpected error whilst trying to
store log entry. Log messages could be lost.

{noformat}
Though the logging of the repeated message can be switched off using a
BrokerLogInclusionRule targeting the BrokerLoggerStatusListener class, it would
be beneficial to make BrokerLoggerStatusListener logic more flexible, logging
stacktraces on lower log levels (DEBUG, TRACE) only.
