We encountered a strange behavior if we change the prefetch size for the consumers. We have two threads that receives message. The first one fetch some messages and is then interrupted without closing the connection to the broker. If the second thread is created it can't receive any messages. In this scenario we don't changed the default prefetch limit.
So if change the prefetch to 50 for example, the second receives messages. This works. If we set the prefetch limit to 600 or above, the second thread receives some message but slows down till no more message is received. This behavior isn't understood by us because the prefetch size is the number of messages the broker will deliver to the consumer without acknowledge these. In the queue that we are using are enough messages to consume by the clients. -- View this message in context: http://activemq.2283324.n4.nabble.com/Unpredictable-behavior-of-the-ActieMQ-broker-if-the-prefetch-size-is-changed-tp3297083p3297083.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
