Lars:

Let me start off by making sure that you and your user know that
"fs flush" is used to flush a single file.   If you want to flush
a volume you use "fs flushvolume".   In RC4 there will also be
"fs flushall".  (RC4 is being packages as I write this.)

If you can replicate the situation on a regular basis you can
attempt to debug it using a network monitor and the AFS Client
trace logging on the machine that is failing to see the changes.

You will want to increase the trace buffer size to something
huge (50,000 entries).   See afs-install-notes.txt for debugging
tips and registry.txt for the locations of the registry values.

Once you have an afsd.log and network trace that demonstrates
the problem, send them as part of a bug report to
openafs-bugs@openafs.org.

The most likely issue is that the client is not receiving a
callback break.   If this is machine that is assigned random
IP addresses it could be a problem that is fixed in the server
in the 1.4.0 RC1 release.   Or it could simply be that the client
is behind a firewall/NAT that does not keep the UDP port open/mapped
long enough for the server to be able to successfully send the
callback break.
