Thanks for all the suggestions. I've modified the patch for all of them. (tx/rx instead of snd/rcv, _tls at the end of the names so the order is more readable.) There aren't really errors visible at the RPC/TLS boundary, but I have added counts of successful/failed handshakes and a count of alert messages (basically "Peer Resets" from what I've seen). Thanks, rick ps: Just replying to one of the messages and, yes, I did top post..
