> ActiveMQ currently doesnt evict expried messages from the Dead Letter Queue. This can potentially lead to Out Of Memory situation as by default the broker keeps all messages in memory. One possible strategy is to modify ActiveMQ broker configuration to spool messages from the DLQ to disk when memory is tight. Other strategy may involve creating a custom DLQ Consumer to drain messages.
