X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 08 May 2003 15:02:49 -0000 Hi, I noticed that my 4.8R box seems to have a NFS problem. I use a FreeBSD/i386 4.8R box as a NFS server, and a FreeBSD/i386 5-CURRENT (as of today) as the NFS client. On the client, /a (on the server) can be mounted successfully with -o rw,bg,intr,mntudp options. However, when a large amount of write operations such as "cp -r /home/ncvs /a" are performed on the client, the transfer is unexpectedly stalled and "nfs server xxx:/a: not responding" is reported. A long time (about 10-20 minutes) later, the operations are finished. During the stall, tcpdump on the server says repeatedly the following: 23:44:43.050494 nfsclient.1731995803 > nfsserver.nfs: 1472 write [|nfs] (frag 33263:1480@0+) 23:44:43.050506 truncated-ip - 2 bytes missing! nfsserver > nfsclient: udp (frag 33263:224@1480) Did anyone experience this symptom? I tried NetBSD/sparc64 as a NFS client, but got the same result. -- | Hiroki SATO /
