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.

*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.

Thanks,
