Hi,
I'm running ActiveMQ version 5.6.0 on linux.
Very occasionaly a message ends up on a DLQ even though consumer logs give
every indication that the message has been successfully delivered and
processed.
The consumer Spring jms listener acknowledge attribute is set to "client"
I can't find any errors or warnings logged that relate directly to these DLQ
events but I have found a few JDBC warnings in the log.
Here's an example.
WARN o.a.a.s.jdbc.JDBCPersistenceAdapter - JDBC Failure: Io exception:
Connection reset java.sql.SQLRecoverableException: Io exception: Connection
reset

Could a JDBC exception be forcing a message onto the DLQ after delivery has
been acknowledged?
Thanks,
