samba - Jun 2018 - Bad message_id occasionally when connecting a MacOS to a freebsd running 4.8.2

Hi,
I am running Samba 4.8.2 with fruit and use it to connect a MacOS to the server.
Mostly it works very good, but occasionally the connection halts or the Mac
disconnects, and in the log I find these messages:

Is there something I can do?

My suspision here is with the MacOSX SMB2 credit handling. Have
you asked Apple ?

I’ve sent also to Apple, but no reply there yet.
