[Samba] file locks problem??

[Boogerman]

I suggest you get the latest samba version.
I've been having similar problems with older versions, wich I solved
disabling kernel oplocks:

kernel oplocks = no

If that doesn't solve your problem, try also

level2 oplocks = no
oplocks = no

(note that this will reduce the performance since clients will no longer be
able to cache files, so I suggest you get a newer samba/kernel)
