Again, please help: cannot copy a file (SMBnttrans/SMBntcreateX)

[Jörg Leinhoß]

Hi,

I post this message again because we have massive problems copying files to a samba share. The described scene - copy two file a or
b - is only a simplified exapmple! I upgrade the linux kernel to 2.4.9 (samba is 2.2.1a) and the problem remains. Please help!!!

The captured logs (log.smbd log level 5):
try to copy file "a" (don't work): http://www.aed-graphics.de/a.log.smbd.txt (below line 67)
copying file "b" (works): http://www.aed-graphics.de/b.log.smbd.txt (below line 77)

Thanks and Regards,
J.Leinhoss
