[Samba] Really Funky Samba Errors (smbd/nttrans.c:call_nt_transact_ioctl)

[William R. Lorenz]

Hi All,

I'm experiencing some really funky Samba errors, and I'm hoping that some
of you might have some ideas.  This only happens sporadically, and when it
does, I loose Samba connectivity for a while.  Here are my Samba logs:

  Jun  2 13:29:01 nasone smbd[20289]: [2004/06/02 13:29:01, 0] 
    smbd/nttrans.c:call_nt_transact_ioctl(2076)
  Jun  2 13:29:01 nasone smbd[20289]:   call_nt_transact_ioctl(0x9009c): 
    Currently not implemented.
  Jun  2 13:45:22 nasone smbd[20289]: [2004/06/02 13:45:22, 0] 
    lib/util_sock.c:read_socket_with_timeout(304)
  Jun  2 13:45:22 nasone smbd[20289]:   read_socket_with_timeout: timeout 
    read. read error = Connection reset by peer.
  Jun  2 13:45:22 nasone smbd[20289]: [2004/06/02 13:45:22, 0] 
    smbd/oplock.c:oplock_break(801)
  Jun  2 13:45:22 nasone smbd[20289]:   oplock_break: receive_smb error 
    (Connection reset by peer)
  Jun  2 13:45:22 nasone smbd[20289]:   oplock_break failed for file 
    GENSRVNT/Bin/Mercury.exe (dev = fd03, inode = 786527, file_id = 475).
  Jun  2 13:45:22 nasone smbd[20289]: [2004/06/02 13:45:22, 0] 
    smbd/oplock.c:oplock_break(891)

I did some poking around in the code, but I don't know enough about the
underlying NT IOCTL functionality to really make heads or tails of it.  
The machine hitting the Samba server is a Windows 2000 Server box with
Service Pack 4 installed.  I would assume this should be well and
supported in all of its funky NT IOCTL calls.  Does anyone have ideas?
