Hello, I have ActiveMQ setup which configured with network of brokers like below. The central ActiveMQ connects with different locations of ActiveMQ brokers in durable subscriptions for both Queue and Topic and on 20K consumers are connected with that different locations of ActiveMQ broker. There is a producer client called MCollective which am using to publish message to central ActiveMQ and those messages will forwarded to each locations of ActiveMQ brokers and the connected 20K consumers will get that message, do stuffs accordingly and put the response back to queue. So those response back messages will be consumed by single consumer which connected with central ActiveMQ broker.
The problem is when I publish message to of all those 20K consumers then central ActiveMQ get stuck and its not accepting any messages to publish until those messages consumed and returned response messages also consumed by the consumer. Once all of those messages consumed then it back to normal. But the each locations of ActiveMQ broker is fine. I suspect some dead lock is happening on the central ActiveMQ and would like to understand why its happening and how to tune ActiveMQ to fix this issue to work with any amount on messages. Thanks Ravi
