Hi, We have a TLS Server (Written in C) and Client (Written in Java using Netty + OpenSSL). I see that when Server sends a TLS extension Heartbeat request to client - OpenSSL responds to it and sends a close_notify alert right after it - causing the server to close the session with client. I don't have any callback registered in client (HB request recipient side - Java/Netty doesn't really have that support) and so I'm sure that it is OpenSSL by itself is responding to that heartbeat request. But, who or what is making OpenSSL to send an alert & close the session upon responding to heartbeat remains a mystery. Any help / suggestions to investigate this issue is highly appreciated.
