[rabbitmq-discuss] rabbitmq gets high load

[Doug]

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
17994 rabbitmq  20   0 11.6g  10g 1764 S  367 66.2 416834:07 beam.smp

As you see, rabbitmq process has lots of system load (367% CPU, 66.2% memory).
It even can't list the queue now:

root at ubuntu:~# rabbitmqctl -p /pay list_queues
Listing queues ...
^C
BREAK: (a)bort (c)ontinue (p)roc info (i)nfo (l)oaded
       (v)ersion (k)ill (D)b-tables (d)istribution


So how to handle this case? Thanks.
