command 50 is SMB Transact2 (used for various types of operatoins including to handle stat,
ie Transact2 QueryPathInfo, as well as setting file attributes, querying fs info etc.)
Normally if the server would not respond that is a server or server filesystem bug, but
you could confirm that with an ethereal (or tcpdump) network trace of the traffic.
You also might check the number of reconnections to see if the client is retrying a lot
(resetting up the session after the failed command) - see /proc/fs/cifs/DebugData

That is not a server that I recognize.  Would be interesting to run Samba 4's smbtorture test suite to see how complete their implementation is.
