For some time now I've been trying to track down a problem with
my Samba server. It is set up as a PDC running RH 7.2 with kernel
2.4.18, samba 2.2.3a. Now I've run MANY different versions and kernel
compiles. Starting with RH default. And working up. This problem seems
to have started when I moved to Win2k. As a test I installed XP. I
experience the same issues. I've changed out the NIC, cable and switch,
moved IRQ's from here to Tuesday. ;-) The system is a K6II 350 with 256
Ram, and 2 intel pro 100+ cards. I tried a set of 3 com cards also. The
real problem seems to be when I copy files larger than ~10 Mbytes. The
transfer starts then it seems to hang, it locks up and either claims the
system resource is no longer available or the path is too deep. I've
checked both system logs and Samba logs, there are errors in the samba
logs below but when I tailed them out, the errors occur only after I've
tried to copy the file a second time after system recovery. I've read on
the archives over and seems identify that some of the problems were
hardware related however I'm %90 sure I've swaped out everything. Since
the problem seems to be specific to the Win2k and up systems I'm leaning
towards some call procedure. Any help would be appreciated this problem
is quite annoying especially for someone who does Audio editing for a
major theatre.

Probelms Writing large files to sambaDoes this problem happen when transferring
to any share or partition? Does this happen with all Win2K systems or do you
only have one to test with? What is the file type of the files you are
transferring? Does it happen with all file types or just certain ones? Have
you tried removing the 'interfaces' line to see how it acts when it uses
the information provided by the kernel? (default is all interfaces; eth0 and
eth1) Do you need it to only use eth1 for a specific reason? Have you tried
disabling oplocks or setting the veto for certain filetypes?
