GET request hung when body is large(~1M)

[eugenekainara]

Hi,

I'm trying integrate Eureka server, spring-cloud-gateway and my spring boot application, but I'm see some requests that hung. I've found that issue reproduces only when request body is large.

For STR see example

Turning on debug, I see

Disabling netty http client pooling fixed the issue for me ☹️
