How many<br>queues are there? 1000? And how many connections?<br><br>yes 1000 queues and 1000 connections. this 4 GB was after 200 GB messages were consumed.<br>If the broker is started fresh with 1000 queues and connections but no messages published, the mem usage is 260 MB.<br><br>> How frequently are you running 'rabbitmqctl list_queues'? If it is run fairly frequently it can significantly delay freeing up memory since queues don't get a chance to hibernate.<br><br>we run it once a minute to monitor the queue length. i will disable it in my next test.<br><br>thanks.<br><br>-alex<br><br></div></div></div><br>
