   ## Environment details:
   
   * local deployment, native ubuntu, Mac OS, Kubernetes, ...
   * version of docker, ubuntu, ...
   
   ## Steps to reproduce the issue:
   
   1.   https://github.com/apache/openwhisk/blob/master/core/controller/src/main/scala/org/apache/openwhisk/core/loadBalancer/FPCPoolBalancer.scala#L741
   this line is used to choose a scheduler by the FPCPoolBalancer. And it uses the queueSize as a base to get a scheduler with the least queueSize. But I searched the whole project, the queueSize is not updated after this scheduler creates a new queue. Is this a bug? or we should use the API getQueueSize (for schedulercore) to replace the code here?
   
   
   
   ## Additional information you deem important:
   * issue happens only occasionally or under certain circumstances   
   * changes you did or observed in the environment

   Hi @blossomin no this is not a bug. The queueSize is updated whenever the schedulerEndpoints trieMap is reloaded from etcd. The schedulers are responsible for updating how many queues are running them to the db, then the controllers will periodically reload this data. See L563 of the FPCPoolBalancer, the function called `loadSchedulerEndpoint()`.
