[Samba] smbXsrv_client_connection_pass_loop: smb2srv_client_connection_passed() failed => NT_STATUS_OBJECT_NAME_NOT_FOUND

[Andrew Bartlett]

Can you set up another environment similar to production that does
reproduce this?

Either way, I've sent an invite to you and Haihua for our bugzilla to
let you file a bug for this, and to fill in what details are known. 

Hopefully someone who knows this code well can help out with any
further debugging steps.
