> 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.
