Yes, I agree, locking is a serious problem. The whole thing runs with Linux NFS servers for a couple of month now (though I want to migrate to OSX NFS servers), and I introduced fake oplocks = yes in smb.conf some month ago (which obviously improved stability) and did also some experimenting with the -L-option of mount_nfs. Thank you very much for reply!

OSX NFS-Server FreeBSD NFS Client
I observe a serious problem with NFS exports from a Mac OS X 10.4 server to FreeBSD 6.2 NFS clients (itself running on DELL PowerEdge 2850 server hardware). We use the StorNext distributed file system in which FreeBSD cannot participate straightly (sorry to say). But OS X can do using the XSAN software from Apple, so we integrated the OS X server into the StorNext environment. We want OS X to NFS export the filesystems to FreeBSD clients, which by itself for example act as SMB servers using Samba 3.0.x. After exporting and mounting, everything seems to work well. But when the system gets under some real life load, NFS-mounted file systems begin sporadically to hang on the FreeBSD clients without any error message. On the NFS clients, although some processes are blocked in kernel mode when accessing files, others still can work successfully. But with increasing time, the situation becomes worse and worse until we have to restart the operating system by ungently switching the power off and on again. The OS X server seems to be unimpressed by all this. I'd greatly appreciate any hint or idea what to do. Of course, I did some experimenting with NFS mount options (-rsize,-wsize,-L), but got no improvement.
