Hi all, Have been using samba with all my Windows XP professional clients for sometime now. All have been worked well until a problem has recently discovered. I was not able to send a large file over the network to my linux server (running samba). The file is an around 700MBs XviD file (size is fairly below 2GB). My samba log returns errors below: smbd[7389]: [2003/03/11 03:03:36, 0] smbd/oplock.c:oplock_break(790) smbd[7389]: oplock_break: end of file from client smbd[7389]: oplock_break failed for file file.avi (dev = 1601, inode 28097, file_id = 486). smbd[7389]: [2003/03/11 03:03:36, 0] smbd/oplock.c:oplock_break(878) There is no problem transferring small sized files to the samba mount drives. A strange thing is that transferring that file works when destination is home directory (e.g. /home/user, if logged in samba with username, user). Other mount points, it will not work (no matter filesystem type, fat32 partition, linux partition...etc). Haven't had any other files at that size to test but is it possible it's something to do with the file format? Any help would be very much appreciated. Thanks a lot! Johnny
