Error description
The problem has been replicated using the amqsevt sample, run as follows with the "-r r" flag. /opt/mqm/samp/bin/amqsevt -m TEST -c -r r -t myTopic/testTopic After a network break, it is expected that a reconnectable client application should reconnect and continue to display messages published to the myTopic/testTopic topic. However with amqsevt, after the break, new messages no longer appear in the terminal. Other reconnectable MQ client applications may similarly not receive newly published messages after a network break. Queue manager traces confirmed the messages are published and consumed but not being displayed to the terminal.
Local fix
