Since i am neither familiar with kernel sources nor with the internals of NFS: Could you show me, where the bug can be traced, i.e. at which point one can detect that the stream is out of sync? I would like to insert another log() in order to see, if - the error occurs at all - is in any way related to our problems. --Heinrich
