What do you have networkTTL set at? Also, depending on how the brokers are interconnected, you may want to consider setting dynamicOnly to true; this ensures that messages are only routed to brokers with active consumers.
Careful using 'duplex' bridges between brokers in combination with high networkTTL settings. Messages will bounce around needlessly. This has been patched, but make sure you have it. http://issues.apache.org/activemq/browse/AMQ-1661 Hope this helps, Joe Get a free ActiveMQ user guide at www.ttmsolutions.com aburgel wrote: > > hi, > > i have a network of 4 brokers. i've created a queue where each broker has > 1 producer, and only 1 of the brokers has a consumer. i'm running activemq > 5.1. > > about every third or fourth message i produce on one node will not end up > at the consumer. > > via jmx, i can see that the brokers all have a connection to each other, > so there's no connectivity issue. > > i have turned on the logging plugin, so i can see that the message is > created and sent out. when the message is successfully delivered, i see it > go directly to the consumer node. when it gets stuck, it goes to each of > the other two nodes and then stays put at the last one. > > if i restart the node where that message is stuck, then it will be > delivered to the consumer. but otherwise it just sits there. > > i have a bunch of logs that i can post if its helpful. i modified the > logging broker plugin to log more info, specifically when consumers are > added and removed. > > when the nodes start up, i can see that the consumer for this particular > queue is added on all the nodes, tho sometimes the brokerPath is > different. > > is it possible that the routes between the brokers are looped or in some > other way causing a message to get stuck? > > is there a way to get that stuck message to move again? it seems a bit > strange that it would just sit there for ever on a node with no consumer. > > i have logs and my config. if that would help, let me know and i'll post > it. any help is much appreciated. > > --alex > -- View this message in context: http://www.nabble.com/tracing-stuck-messages-in-network-of-brokers-tp17395138s2354p17396466.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
