[Samba] Large file problem with version 3.0.34

[Alejandro Escanero Blanco]

I have a problem with large files (>2 Gb) in a Debian sarge based system.
I install samba 3.0.34 with this configuration:
./configure --with-smbwrapper --with-ldap --with-automount 
--with-smbmount --with-pam --with-pam_smbpass --with-ldapsam 
--with-syslog --without-profiling-data --with-quotas --with-sys-quotas 
--with-libsmbclient --with-acl-support --with-utmp --with-vfs 
--with-winbind --localstatedir='/var/lib/samba/locks' 
--prefix='/usr/local/samba' --mandir='${prefix}/man' 
--exec_prefix='${prefix}' --sbindir='${exec_prefix}/sbin' 
--bindir='${exec_prefix}/bin' --sysconfdir='/etc/samba' 
--with-configdir='/etc/samba' --with-lockdir='/var/lib/samba/locks' 
--with-logfilebase='/var/log/samba' --libdir='${exec_prefix}/lib' 
--with-piddir='/var/lib/samba/locks' 
--with-privatedir='/etc/samba/private' --with-swatdir='${prefix}/swat' 
--enable-cups

Kernel is a 2.6.8
I uploaded two files of 2,2Gb and 2,9 Gb and i can't get it from a 
Windows XP or a smbclient.
The log (level 10) says:

But the user can access without any problem, the file is uploaded by the 
same user via scp.

I can't find information why samba can't access the file.

Thanks.
