Hi
We have 3 quesitons.
Could you please check them?

[Phenomenon]
We create an application that uses the JSON-RPC2.0 API.
If call a large number of APIs for a certain period of time, the following HTML will be returned instead of the JSON-RPC response.

Heavy load detected!

                
We're sorry, too many people are accessing this booking page at the same time

            Heavy Load image

[Question]
(1) Is this the specificatio?
(2) Please tell me the conditions under which the above Heavy load detected! is returned. For example, “When the number of APICalls per second exceeds 5 and continues for 1 minute”
(3) If (2) is caused by the resource status (CPU usage rate, etc.), please let me know if there is an effective countermeasure.
For example, leave an interval between API and API calls

Best Regards,
Kei
