Was some other process able to take that lock (or even delete the file, doh+ACE-), before your client could reclaim it? That said, if the server is Oopsing, then you have a broken server. I'd suggest posting that Oops to this list first. -- Trond Myklebust Linux NFS client maintainer NetApp Trond.Myklebust+AEA-netapp.com www.netapp.com -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
