nfsmount failed; bad file descriptor

[janwinte]

Since a few days, my OTC clients will not start anymore. I receive following errors:

mount: RPC: Unable to receive; errno = connection refused
mount: nfsmount failed; bad file descriptor
mount: Mounting 10.101.2.40:/openthinclient on /root failed: Invalid argument
cp: unable to open '/root/etc/': Is a directory
mount: Mounting /dev on /root/dev failed: No such file or directory

Does someone has any idea what can be causing this issue ?
Thanx
