The official status is as that note in documentation says. We want to
harden it and input from you like this is very important. Please share
dumps, logs, failure scenarios, whatever that is not working as expected.
Create issues or continue questions/discussions at discuss.akka.io

Thanks,

Hi all,
2.5.10 akka release notes state "However, since itâs a new implementation
the TCP/TLS transport is not ready for usage in production yet, but please
test it and report any issues." and we have the same warning on remoting
docs page. What's the actual status on this? Anyone using it for extended
period of time? We've tried switching from netty to artery tcp (akka
2.5.13) and testing seemed to be ok, on production we are seeing some odd
- steady increase of memory consumption (have to dig deeper to take some
dumps, but memory graphs indicate this across all cluster nodes), it also
seems that memory usage increases in other nodes if one node gets
terminated unexpectedly (e.g. killed by kubernetes because of OOM)
- nodes randomly failing to join cluster after restart (we use autodown)
From the logs when joining fails there are a lot of messages with
"akka.stream.Materializer - [outbound connection to [akka://
Association$OutboundStreamStopQuarantinedSignal$:"
