netty: SSL failures Netty 4.1.13 -> 4.1.14

I have fallen a little bit behind in the Netty releases and am in the process of upgrading from Netty 4.1.13 w/ netty-tcnative 2.0.5 (linux, openssl, custom static build) to Netty 4.1.14 with same netty-tcnative version.

We’re observing a failure where SSL is slowly failing and becoming more unreliable over a course of a couple of hours. Unreliable as in handshakes failing/hanging. It’s a degrading failure with no apparent external metrics such as servers running of memory or more CPU being consumed.

I’m going to bisect the 4.1.14 commits and hopefully find the source but if you’ve got ideas then let me know.
