I've done some more investigating and managed to get a couple of level
10 debug logs from affected clients.  I had originally wondered if
this might be a networking issue, but I'm now pretty certain that it's
a Samba issue.  Each time the problem happens, from what I can tell
from looking at the logs, the server sends the client a message as
usual (reply_ntcreate_and_X in two instances, reply_ntcreate_and_X
then call_nt_transact_notify_change (?) in another), then it tries and
fails to read the next message:

[2007/06/08 14:02:21, 10] lib/util_sock.c:read_data(525)
  read_data: read of 4 returned 0. Error = Success
[2007/06/08 14:02:21, 10] lib/util_sock.c:receive_smb_raw(672)
  receive_smb_raw: length < 0!
[2007/06/08 14:02:21, 3] smbd/process.c:timeout_processing(1328)
  timeout_processing: End of file from client (client has disconnected).

Is anyone else seeing similar problems?  Should I open a Bugzilla or
post the full debug logs here?
