Description
We use spring cloud gateway to route user requests to the downstream systems. When gateway is under load, it is observed that the few requests sample are being dropped abruptly. The distribution is sparse, we observe this for 2% of the requests. When the event occurs, the user is being returned a 200K response with empty response payload. Is this a known behaviour/anyone faced it before & resolved it? It will be of help if there is any direction to since the occurrence is very rare.
The spring cloud gateway version that we use is 3.0.x

Research direction
Start by reproducing the reported behavior with Spring Cloud Gateway 3.0.x under load, using the issue's details as the baseline: approximately 2% of requests receive a 200 response with an empty payload. Correlate gateway and downstream request/response logs to determine where requests are lost; done means identifying a reproducible cause and a verified resolution or clear explanation.
