Hi,<div><br></div><div>Now i'm running RabbitMQ in 3 hosts in cluster mode, each Rabbit nodes run in disc mode, </div><div>but I found that even there is no produce and consume operation going on, the % cpu usage </div>
<div>remain very high especially on the master node. </div><div><br></div><div>Below are the TOP result captured in the hosts:</div><div><br></div><div><b>Master Node</b> </div><div><div>PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND</div>

<br></div></div><div style="font-weight:bold"><br></div><div>Based on the result captured on the hosts the memory usage is OK, but why the </div><div>%cpu usage can be so high? Is it due to my server configuration?</div>
