I all so appear to be getting this error. I have enabled 'debug level =
3' in my smb.conf so am waiting for another error to get some more
information. It happens a random amount of times a day. It appears to
happen when you connect to a share or try to open a file on the share. I
have only experienced the problem on Windows 7 client but I don't access
the share often from Ubuntu clients.
