As you explained in your question, it seems connection between the client and the server has timed out. These kind of lagging can be happen due to the back-end slowness or the ESB server contention. Hence Increasing time out settings could be solve this problem.

By default the ESB closes the connection after 60 seconds. So even you increased the client(which send the request)the timeout the problem will not solve.

For your information in WSO2 ESB can set three types of timeouts:

  1. socket timeout - This parameter will decide on the timeout which a particular http request is waiting for a response.

  2. endpoint timeout - This will help to configure timeout per endpoint.

  3. synapse global timeout - This will decide the maximum time that a callback is waiting in the ESB for a response for a particular request.

Please refer below links [1], [2] to find more detailed information about WSO2 ESB Error Handling. Hopefully it will help you to solve the problem.
