> Stratos is creating more instances than the max limit
> -----------------------------------------------------
>
> Key: STRATOS-779
> URL: https://issues.apache.org/jira/browse/STRATOS-779
> Project: Stratos
> Issue Type: Bug
> Components: Autoscaler, Cartridge Agent, Cloud Controller
> Reporter: Rajkumar Rajaratnam
> Fix For: 4.1.0 M1
>
>
> Currently, call from AS to CC to spawn new instances is synchronous. It has a
> timeout. Hence, there can be a situation like below,
> Call from AS to CC to spawn new instance can time out.
> Due to that, AS will not add the pending member for that call.
> But CC's attempt to spawn the instance can become successful with a very high
> delay (> time out)
> Meanwhile, the agent can send the instance activated event, even before CC
> sends the member started event. Since this member is not there in the
> topology, the event will get discarded. Hence, the member will never get
> activated in topology, and remains in created state. This is an additional
> member!
