I'm not sure if it's related, but i've noticed under HEAVY nfs load my nfs server hangs for a while, then it REBOOTS! i'm pretty sure it's a nfs related problem, because doing heavy disk i/o on the server itself doen't have any related problems at all.. only when it's heavy access over nfs. I'm going to try makeworld again today, maybe it was a bug that has been fixed. we'll see > >On several clients (-DP1, -DP2, 4-stable) mounting a nfs-share > >(mount_nfs -i -U -3 server:/nfs /mnt) and then copying data from that > >share to the local disk (find -x -d /mnt | cpio -pdumv /local) results > >in lost NFS-mount. > > > >client kernel: nfs server server:/nfs: not responding 10 > 9 > > I'm not sure what you mean by a "lost" mount.
