Title:
  periodic keystone query for active instances

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  I'm running based on Grizzly with quantum+OVS+vlan.
  When I have an active instance in the cloud, I noticed about a periodic keystone query from the compute node with the active instance. Each time, the compute node requests 4 new tokens.
  Anyone know why this happen ?

  I notice some logs in nova-compute.log, but not sure if it is related:
