How do you "copy ... over smb"? Are you using smbfs (smbmount) or
smbclient?

smbfs at least does not yet support large files.

I have PC with W2K and server RH6.2 with samba server version: 2.0.7, I
don't copy files up to 2GB ?

thank you very much Urban, I download samba-2.0.7-20000425.src.rpm and with
this package your patch is OK, samba-2.0.7.tar.gz(samba.lates.tar.gz) on the
samba.org website is update and configure script is different from origin
samba-2.0.7:((

Does Samba have a problem with files over 4GB in size? We are seeing files
loop, as they are written past the 4GB limit. Perhaps there's an option I
haven't been able to find and set.

I'm sorry, I should have been more specific on the Samba version. This was
tested with the tip of SAMBA_2_2 from Friday. I will repeat the tests myself
to make sure. I'm reporting other people's results, which is why I'm
not
being exact. I just compiled the tip, so I'll try that.

Thanks for the extra info..... :-). Known bug I fixed in the SAMBA_2_2
CVS tree. Should be fixed in 2.2.3, but you can CVS checkout now and
test to make sure (that would help thanks).

Hi All,

To allow the support of file larger then 2 gigs the following  patches were 
applied the system mentioned below.

CPU: Pentium Pro
Memory: 64 Megs
Kernel version: tried with 2.4.18 and 2.4.20, same errors
Distribution Debian Woody (aka 3.0)
Samba version: 2.2.3a-12
Smbfs patch version: 2.4.18 had patches applied from here :
http://www.hojdpunkten.ac.se/054/samba/index.html
2.4.20 had patches (modified from above) from here:
http://www.ps.uni-sb.de/~errror/smbfs-lfs.html

When coping files even files smaller then 2 gigs in size I get the 
following error message.

cp: cannot stat `/dosworld/pent14/c/Program Files/Trend PC-cillin
  6.0/WHATSNEW.TXT': Too many open files in system

Tar of a SMB mounted directory also yield the following error message 
sometimes.

smb_lookup : find foo.tif failed, error = -23
tar: foo.tif : cannot open; too many open files in system.  Checking the 
file handles available showed that I am not even close to using them up.

The following message occasionally appears on the server console, though I 
do not know if it is related with the above problem

smb_instantiate: foo.tif failed, error -23, closing 186

When I roll back the changes and tested with the same files none of the 
above errors occur.

Can anyone shed some light on what I may be doing wrong?

Thanks in advance.
