Internal cause codes & Session callbacks

[DarioCrivelli]

I confirm that, upon the above kind of closure, the Server finds the socket closed by the client.
So, the Server can no longer send updates to the client and it can only wait for the client to connect again and open a new session.
When the client resubscribes to the same items, the lost updates can still be sent to it as part of the snapshot. The way depends on the subscription mode and other subscription settings.

If you see many 38 closures at the same time, that could be caused by an interruption at network level.
Serious problems on the Server side, leading to repeated "current delay ..." log messages could also cause that.
If you see many subsequent 38 closures for the same client, client side problems are also possible; see this thread, for instance.
