[wildfly-dev] Intra-process connections to ephemeral ports

I've be doing some tests with WF 10. I've noticed that are some connections being established intra-process to and from ephemeral ports. This is without having any application deployed. C:\>netstat -nao | findstr 28692 TCP 127.0.0.1:8280 0.0.0.0:0 LISTENING 28692 TCP 127.0.0.1:10190 0.0.0.0:0 LISTENING 28692 TCP 127.0.0.1:64778 127.0.0.1:64779 ESTABLISHED 28692 TCP 127.0.0.1:64779 127.0.0.1:64778 ESTABLISHED 28692 TCP 127.0.0.1:64780 127.0.0.1:64781 ESTABLISHED 28692 TCP 127.0.0.1:64781 127.0.0.1:64780 ESTABLISHED 28692 TCP 127.0.0.1:64782 127.0.0.1:64783 ESTABLISHED 28692 TCP 127.0.0.1:64783 127.0.0.1:64782 ESTABLISHED 28692 TCP 127.0.0.1:64784 127.0.0.1:64785 ESTABLISHED 28692 TCP 127.0.0.1:64785 127.0.0.1:64784 ESTABLISHED 28692 TCP 127.0.0.1:64786 127.0.0.1:64787 ESTABLISHED 28692 TCP 127.0.0.1:64787 127.0.0.1:64786 ESTABLISHED 28692 TCP 127.0.0.1:64788 127.0.0.1:64789 ESTABLISHED 28692 TCP 127.0.0.1:64789 127.0.0.1:64788 ESTABLISHED 28692 TCP 127.0.0.1:64790 127.0.0.1:64791 ESTABLISHED 28692 TCP 127.0.0.1:64791 127.0.0.1:64790 ESTABLISHED 28692 TCP 127.0.0.1:64792 127.0.0.1:64793 ESTABLISHED 28692 TCP 127.0.0.1:64793 127.0.0.1:64792 ESTABLISHED 28692 *Setup* Wildfly 10 final (just downloaded / no applications deployed / port offset:150) Windows 7 64bits Java 8u20 Can someone clarify why is this happening? Or provide some troubleshooting tips? *Connection pattern* Using WinCap I was able to identify the communication pattern: Client Connects [SYN] Server Ack [SYN, ACK] Client Ack [ACK] Client Push [PSH] - It pushes 8 bytes (e.g., in hex, e6202552f2b95f6f) Optionally the server pushes some data periodically (always the same) Server Push [PSH] - It pushes 1 bytes (in hex, 1) I've reported a problem related with this in the user's forum, but I still don't have a answer.
