NFS oddities with MacOX X clients

[manu%netbsd.org@localhost (Emmanuel Dreyfus)]

Hello

I have a NFS server that has frequent crashes which I suspect to be
caused by MacOS X NFS client.

Last problem encountered: a directory gets inaccssible:
ls -ld directory fails with "bad file descriptor", so does stat(1).
hexdump directory shows only zeros. cd says that the directory does not
exist.

I tried to unmount to run fsck, the umount command got stuck (in vnode)
and was unkillable by kill -9. The filesystem was unmounted anyway, but
fsck would hang without doing anything on it. It was possible to kill
fsck, though.

Dropping in single user does not improve. An attempt to reboot caused an
attempt to sync the disks (it gave up) , and ended with the machine
frozen on its console. It was still possible to get into ddb, but a
reboot from ddb did not manage to restart the machine.

After reboot, the filesystem is in an ugly shape and needs a manual
fsck. See below. Isn't it horrible?

Anyone experiencing the same troubles? This is netbsd-5 from 2008/11/08
