Karate-netty 1.5.1 memory leak

[gboujaou]

I see memory leak when using karate-netty (karate-1.5.1.jar) as a mock HTTP.
Heap usage increases over time and eventually causing the mock server to restart
I started a simple karate-netty mock server using Karate's built-in mock server API with a small feature file.
Run a client that issues 200 requests per second.
After 3 hours the mock server restart
