I'm seeing some weird behaviour with a NFS-server (-current as of today). 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 seeing this only while using UDP; with TCP everything works fine. The amount of data copied before it stalls is related to the number of nfsd-workers on the server. With 8 nfsd-processes (/usr/sbin/nfsd -u -t -n 8) running more data is copied before the mount gets lost. (The network works fine) Any hints? TIA, Patric -- The problem with troubleshooting is that trouble shoots back. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
