I've set up a cluster of Rabbits with 3 nodes (16GB RAM, 4x cpu cores each) and a Load Balancer in front of them, increased all of the system limits on sockets and file descriptors, but can't seem to scale to more then 30k connections on the entire cluster.�</div>
<div><br></div><div>Each connections has it's own exchange and a temporary direct queue, RAM usage is about 2-3GB on each node and CPU usage peaks at about 200% (which on 4 cores isn't all that bad). At first all is quite well and the cluster manages upwards of 1k msgs/second (I haven't tried more, pretty sure it would handle it). However, after scaling to that many connections, the cluster seems to grind to a halt and eventually nodes become unresponsive. The management API takes upwards of 5 (FIVE!) minutes to retrieve a server summary report. Am I missing something here? Or is this just a bad idea altogether? I was expecting that if each node was able to handle 30k+ connections, I could have a cluster of 50 or so (with multiple balancers, of course!) and live a happy life �;-)</div>
