ningyougang opened a new issue #2809: The Load balancer can't schedule the last invoker when exist more than one invokers
URL: https://github.com/apache/incubator-openwhisk/issues/2809
 
 
   After installed multiple invokers, access `http://controller:10001/invokers`, all the invoker's status is `up`, but when execute `wsk -i action invoke --result <action>` multiple times, the last invoker can't be scheduled by controller's loadbalancer to deal `the action request`.
   
   I do several tests as below(in centos7, memory:16G, cpu:8 physical cpu total, 8 logic cores total)
   * test case one: only deploy two invokers
     status for invokers: {"invoker0":"up","invoker1":"up"}
     only `invoker0` deals the request,  `invoker1` seems don't recevie the request
   
   * test case one: deploy three invokers
     status for invokers: {"invoker0":"up","invoker1":"up", "invoker2":"up"}
      only `invoker0` and `invoker1` deal the request, `invoker2` don't recevie the request. 
   
   * test case one: deploy four invokers
     status for invokers: {"invoker0":"up","invoker1":"up", "invoker2":"up","invoker3":"up"}
     only `invoker0` and `invoker1`  and `invoker2` deal the request, `invoker3` don't recevie the request. 
   
   * test case one: deploy five invokers
     status for invokers: {"invoker0":"up","invoker1":"up", "invoker2":"up","invoker3":"up","invoker4":"up"}
     only `invoker0` and `invoker1`  and `invoker2` and `invoker3` deal the request, `invoker4` don't recevie the request. 
   
   So my test conclusion is that: since all invokers's status is ok, may be there has some bug on controller's `load balancer?s scheduling strategy`, it leads to the last invoker can't be sheduled by `load balancer` to deal the `action request`
