I have been using Kino to edit DV files on an NFS-mounted filesystem.
When I export an edited sequence to a single file, Kino starts to write
frames and then eventually hangs. Sometimes it recovers from the hang
after a few seconds or minutes. In other cases I have given up on it
after about 10 minutes.
While Kino is hung, attempts to list the directory containing the file
it was writing (ls -l) hang, but listing of other directories on the
NFS-mount do not (I suspect that the stat call on this specific file
is hanging). One thing I have noticed when listing the directory on
the client and server *during* an export is that before the hang the
client begins to show a much larger file size (up to 400 MB larger)
than the server. In some cases I have been able to kill Kino, which
sometimes unblocks ls as well. After this, the file sizes become
consistent again.
This does not happen with linux-image-2.6.18-4-686.
