List-Post: List-Help: List-Subscribe: , List-Archive: We are experiencing a problem which seems to be related to data caching on our linux nfs clients; Using Mental Ray, we render picture to an NFS mounted filesystem (I have tried both SGI and Auspex file servers). We have an inhouse application which we use to view the rendered pictures. If you attempt to view a picture which has not completely finished rendering, you get a plain grey window. Once that situation has happened, you cannot view that picture from that machine until you umount and mount that filesystem again. You can view it from other machines however. Most of our machines are running RedHat 7.2 with a 2.4.7-10 kernel and nfs-utils-0.3.1-13. I have tried using RedHat 8.0 with a 2.4.18-14, 2.4.20-28, and most recently 2.6.2 kernel, and nfs-utils-1.0.1-2. Same result. Here the line from the /etc/fstab file for the filesystem that I'm testing on: holly:/images_temp /images_temp nfs rw,bg,rsize=32768,wsize=32768 I don't have this problem with any of our Irix clients.
