Hello, we have several error messages of nfsd on our fileserver which has 4 GB RAM and has only a medium load (see below). The kernel is vanilla 2.6.24.4. Is there an explanation of these errors? The server seems to work after these error messages. Any help is appreciated. Thanks in advance -Ulrich ==================== Apr 15 10:42:53 netsrv1 kernel: nfsd: page allocation failure. order:0, mode:0x20 Apr 15 10:42:53 netsrv1 kernel: Pid: 2474, comm: nfsd Not tainted
