[Samba] fcntl lock failed at large offset: pretty urgent

[Jim Thomas]

The problem appears to be the kernel version.  I have not
verified this on the production machine, just at home with a
subset of the windows client system, but it's reproducible.

Preliminary results:

Linux     Level 1          Range lock
kernel    oplock           just under 2^32
-----------------------------------------------
2.2.25    on               success
2.2.25    off              failure
2.4.22    on               success
2.4.22    off              success

The binary I downloaded was probably compiled on a linux kernel
2.4.x, and I've been running it on a 2.2.25 kernel.  I will test
this at work tomorrow and confirm, but this looks like it.
