Could you be a little bit more specific about the nature of the NFS server: are you using knfsd or is this the legacy userland server? Please also specify what kind of filesystem you are exporting, and the export options you are using. As for the client side, when do these errors occur? Have you seen them occur after a prolonged period of use, or are they more frequent immediately after a reboot or mount operation? Cheers Trond
