Hello ! At my company we are using Apache ActiveMQ 5.18.3. We suspect that in some rare cases, a queue message is read twice by different consumers. For more context : - broker is classic primary/secondary (secondary started but not active - not a network of brokers). - we are using persisted queues with PostgreSQL backend. - A single queue is being read by several consumers : 10 consumers for a single java app deployed in HA other several k8s pods. - We use SESSION_TRANSACTED session for either consumers and producers. - We use PooledConnectionFactory with 1 connection, maximumActiveSessionPerConnection 500, expiryTimeout 10000 We see no transaction or other error in logs, either service of activemq broker at the time of the "double read".
Has something like this already been seen ? Can it be a bug or a misconfiguration somewhere ? Best, Fred
