[rabbitmq-discuss] RabbitMQ Cluster High CPU Usage 100-200%+

[Wong Kam Hoong]

Hi,

Now i'm running RabbitMQ in 3 hosts in cluster mode, each Rabbit nodes run
in disc mode,
but I found that even there is no produce and consume operation going on,
the % cpu usage
remain very high especially on the master node.

Below are the TOP result captured in the hosts:

*Master Node*
PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
13994 rabbitmq  25   0  206m 114m 2304 S *205.0*  2.9 670:29.57 beam.smp

*1st Slave*
PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
13775 rabbitmq  25   0  136m  49m 2252 S *60.7*  1.3   7:02.15 beam.smp

*2nd Slave*
PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
23053 rabbitmq  25   0  135m  47m 2248 S  *8.7*  1.2   8:14.07 beam.smp


Based on the result captured on the hosts the memory usage is OK, but why
the
%cpu usage can be so high? Is it due to my server configuration?
