I copy a file from a Ubuntu 10 machine with openafs-client 1.4.12+dfsg-3

A few questions ...
If you copy the file to a different file name (leaving the original file in
place), does the same problem still exist for that file?

If you flush the cache on the Ubuntu machine (fs setcachesize 1; fs
setcachesize 0) what checksum does the file have on that machine when you
read it back from there?
samuel> sudo /bin/csh -c 'fs setcachesize 1 ; fs setcachesize 0'
New cache size set.

Are you running with disk or memory cache, and what cachesize and other afsd
parameters do you have set?
samuel> cat /etc/openafs/cacheinfo
/afs:/var/cache/openafs:100000
arctura> cat /usr/vice/etc/cacheinfo
/afs:/usr/vice/cache:100000
samuel> cat /etc/openafs/afs.conf.client
AFS_CLIENT=true
AFS_AFSDB=true
AFS_CRYPT=true
AFS_DYNROOT=true
AFS_FAKESTAT=true
arctura> cat /etc/sysconfig/openafs
# OpenAFS Client Configuration
AFSD_ARGS="-dynroot -fakestat"
# OpenAFS Server Configuration
