Did you ever find a resolution?
I know that io.netty.util.IllegalReferenceCountException: refCnt: 0 is used as a way to check/validate functions.
I have yet to understand where there is "0" count. We don't have the issue ever on Val 3 only issue that arrises there is.. lets not go there.
Anyway I was curious if you had any info in your research, thanks again!
