Michael Feingold commented on AMQ-5762:
---------------------------------------

Our tests confirm that there is no memory leaks on the patched version. Thank you. 

Do you know when we can expect the 5.12.0 release? Will the fix be rolled in the 5.10.x and/or
5.11.x?

> When an MQTT connection is closed some memory is not released. In case of the soft close
(calling connection close on the client) memory leaks at the rate of 70K per connection close.
In case of the hard close (pulling the wire, or cutting off the network connection) the leak
goes at the rate of 300K per close. we also checked it on version 5.11 - same problem
