ZERO_COPY and memory leaks
See original GitHub issueHello guys!
I got started updating to the latest rsokcet version and try to use ZERO_COPY. But time to time I catch memory leaks.
Here is my gists example --> https://gist.github.com/segabriel/b8a6a189ff89a9560a279cd97cc4a8fe
I used the following versions:
<reactor.version>Dysprosium-RELEASE</reactor.version>
<rsocket.version>1.0.0-RC5</rsocket.version>
<netty.version>4.1.37.Final</netty.version>
<reactor-netty.version>0.9.0.RELEASE</reactor-netty.version>
An example of exception:
E 2020-01-13T14:16:51,757 i.n.u.ResourceLeakDetector LEAK: ByteBuf.release() was not called before it's garbage-collected. See http://netty.io/wiki/reference-counted-objects.html for more information.

@OlegDokuka Finally got to verify it, it was and is still reproducible on linux only, I mean
RC5version. So I checked my example out again and it seemsRC7version has no such bug, unlikeRC5. So cool, thanks!Most of the leaks are fixed in RC7 now. There are a few more places where leaks may occur, but this will be resolved further since leaks are more related to the Reactor.
@segabriel, any feedback on RC7 is appreciated
