[Samba] Samba panics on disk size and connection is lost while copting files.

[Bo Jacobsen]

I have moved a Samba installation from an old samba 2.2.8a (on a 2.4.21 
kernel) to a new server running Samba 3.0.10 on a SuSE 9.2 (kernel 2.6.8)
and I now have a problem using the (same) shares from client W2K machines. 

When I open "My Computer" window on a client, the drives are marked by a 
red cross, as if they were disconnected, and the disksize is zero.
I can decend into the folders on the drives, and here all the files are there as 
expected. After opening the "My Computer" window, a panic error message 
is logged in log.smbd. The error message is added below.
As long as I'm in a Samba share, the error message is reapeated over and over 
again.

If I copy files to the Samba shares, the operation is interupted after maybe 
600 - 1000MB of files, with a message that the connection to the drive
has been lost. The connection is actually not lost, as I still has full access to the
drive !?. When the copy stops, there is no new error message added to
log.smbd (or log.nmbd).

The problem is exactly the same in both Samba 3.07 and 3.0.10.
The client tested is W2K with SP4 and all the latest fixes installed. Norton 
Internet Security 2003. Disabling the antivirus has no effect.

>From time to time the W2K machines displayes an error message that the 
connection to a Samba share is lost and reestablished.

Any suggestions.
