Is this still an issue with the supported version of spring cloud 4.1.1?

Is this still an issue with the supported version of spring cloud 4.1.1?

yes, the issue still exists.
Please mainly focus on the impact of my changes to the source code NettyWriteResponseFilter.
I added comments to the sample code.

from spring-cloud-gateway.

Can you tell me how to reproduce it?

from spring-cloud-gateway.

Test topology：

1. Jmeter (Constructing HTTP post requests，100 qps is enough)->
2. Spring Cloud Gateway( version 4.1.1 can reproduce and make the modifications according to my previous comments in NettyWriteResponseFilter )->
3. DownStream Services(a netty http server Or a springboot server）

Notes：

• Jmeter runs on Windows10 ，The number of threads in the testing group should be greater than 1
• Every other service runs on a 2-core 4GB Ubuntu virtual machine
• If the number of errors occurring is positively correlated with QPS, then it represents a reproduction
• the errors is Connection has been closed BEFORE response, while sending request body ，Or You can supplement the logs in doOnCancel(() -> cleanup(exchange)) ,which also represents a reproduction
