Jeff Jirsa commented on CASSANDRA-13114:
----------------------------------------

Was this dire enough to go into 2.1 ?  Seems like a pretty high bar for a .17 release.

> https://issues.apache.org/jira/browse/CASSANDRA-12032 updated netty for Cassandra 3.8, but this wasn't backported. Netty 4.0.23, which ships with Cassandra 3.0.x, has some serious bugs around memory handling for SSL connections.
> It would be nice if both were updated to 4.0.42, a version released this year.
> 4.0.23 makes it impossible for me to run SSL, because nodes run out of memory every ~30 minutes. This was fixed in 4.0.27.
