I haven't tried it yet, but I will. There are two points, I want to add: 1) Some people say that UDP mounts have faster transfer rates. I don't know yet, if it's true. 2) I mention the problem with NFS over UDP, because UDP mounts are somehow "fishy", it seems. A robust piece of software should recover from erroneous situations and not get stuck somewhere. The only solution to this situation is an unclean reboot. This is not "nice". -- Martin
