Is there any suggestion? Can you try on an ext3 (or anything that isn't NFS) to see if the problem is due to NFS? I just created a > 2GB file on ext3, over NFS, using dd if=/dev/zero of=bigfile bs=1024k count=2200 I'm appending to it with cat, and it's now up to 3.4GB. Big files don't seem to be a problem for NFS on Linux. I'm using Linux 2.4.22 on the client and server, with the NFS kernel server. Maybe your problem is that lockd isn't running on the server, or something like that? Anyway, I don't think the problem is just because of large files. -- #define X(x,y) x##y Peter Cordes ; e-mail: X(peter@cor , des.ca) "The gods confound the man who first found out how to distinguish the hours!
