Some of the file names are missing from the result and others are duplicated. Tried with 7.2-STABLE FreeBSD and Linux 2.6.32.12 as server, same result. The nfs_bug.py works ok under FreeBSD 8.2. >How-To-Repeat: mount -o nfsv3,rsize=4096,wsize=4096 server:/export /mnt Run the python nfs_bug.py program from http://www.delajii.net/mmWiKi/_media/docs:code:nfs_bug.py >Fix: Mounting the nfs dir with defaults does not show the problem. Changing to nfsv2 or other rsize/wsize combinations seem to be ok (i.e. rsize=8192,wsize=8192 looks ok for now). >Release-Note: >Audit-Trail: >Unformatted:
