WSO2 ESB HTTPS Endpoint, call mediator - But a callback is not registered ( anymore) to process this response error

Question

While using Call mediator and Send Mediator (calling HTTPS endpoint with username token by using policy at the endpoint)

Getting the following error :

[2015-01-03 03:38:23,058] DEBUG - SynapseCallbackReceiver Callback removed for request message id :

I can see the expected response on the console WIRE>> but getting this error and the response is not being correlated

please let me know if anyone has faced this issue earlier and how to resolve this.

Thanks

Answer 1

Reason might be, your service endpoint takes much time to respond. Increase the endpoint timeout value in the endpoint configuration and synapse.global_timeout_interval value in synapse properties file.
