High CPU usage when Q is idle

[benxiong]

Hi guys,

I notice that the CPU usage is very high even when no messages are in the queue, here is the top info:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

    9 root      20   0     0    0    0 R   17  0.0 814:16.15 ksoftirqd/1

Is this a bug? the version is hornetq-2.2.14.Final

Thanks.
