ContinuationStateStack empty warning when using WSO2 ESB

Question

I don't know the reason, but suddenly i got warnings when using WSO2 ESB 4.9.0 APIs like this:

TID: [-1234] [] [2016-08-22 11:26:31,951] WARN {org.apache.synapse.core.axis2.Axis2SynapseEnvironment} - ContinuationStateStack empty. No ContinuationState to mediate the response {org.apache.synapse.core.axis2.Axis2SynapseEnvironment}

I am using a simple call mediator in my service like this:

<call>
  <endpoint>
     <http method="GET"
           uri-template="https://test.com/{uri.var.test}"/>
  </endpoint>
</call>

What causes this? Because my APIs don't return anything (it gives connection timeout)

Connection time out after request is read: http-incoming-2047

What do you have after call mediator? Better if you can post entire synapse config. — Bee

You can set the following property if the API Call is not expecting a response.

<property name="OUT_ONLY" value="true"/>
