Expected Behavior

Actual Behavior

I am running a service with spring gateway based on reactor-netty.

  • spring-cloud-gateway-server: 3.1.8v
  • reactor-netty-core:1.0.39v
  • reactor-netty-core.1.0.39v

I am checking for memory leaks by setting io.netty.leakDetectionLevel=advanced, but I frequently get the following error.

LEAK: ByteBuf.release() was not called before it's garbage-collected. See https://netty.io/wiki/reference-counted-objects.html for more information.

I am guessing that the HTTP request was unexpectedly disconnected on the side that called it, but I would like to ask if there is an issue with the part that I guessed.

The reason I guessed that the http request was disconnected is because the HTTP response status 499 that occurred in NGINX occurred similarly.

Steps to Reproduce

@Test
public void repoCase() {

}
