Quite, but the client is a Windows 2000 box completely idle with
nothing holding the file open, and a good LAN connection.
If an idle client won't release oplocks quickly on request, then
there's a problem. Surely people using lots of Windows clients don't
have to wait 10 seconds or more to open a file which somebody else had
open recently on a different box? I suspect a Samba problem but
anyways the answer is to disable oplocks. It _could_ be a fault in
leases, which is why I asked if they're known to be working.
