Fixed: OpLocks caused the corruptions/slowness (Was: How Samba let us down)

[Claudia Moroder]

Hello,

what does samba if a client locks a byte range behind the end of the file ?
This could be important because it looks like many 'corruption' problems 
happern with foxpro files.
Foxpro uses dbf files like clipper and dbase. All this application does 
NOT lock the real record they want to lock but lock a area at a 2GB 
offset ( or 1 GB, i don't remeber exactly ). They do this to give other 
clients the chace to read locked areas.

Bye
