Hi, I now also tried the mount option 'nordirplus' which is in the shipped with man-page listet only for NFSv3, but on this mailing list it was said is also available for NFSv4. At a first glance this seems also to resolve the problem too, but seems to give better performance than the former mentioned 'lookupcache=none'.
