> Hello,
> When load testing artemis as our MQTT Broker, we detected the broker deadlocks and crashs
(see attached log).
> Our use case is trying 1000 simultaneous connections (publishers) each sending 1 message
per second with 1KB size.
> After all 1000 clients successfully connected to artemis and start sending the messages
after a while the deadlock comes up.
> The Xms and Xmx of the JVM both are set to 4GB
> The broker.xml can be found in attach.
