L.S.,
I just put together a cell (for the first time) for evaluation purposes.
Linux server and linux clients seem to work fine (all running OpenAFS
1.4.8), but I noticed one strange problem:
While running blogbench (http://www.pureftpd.org/project/blogbench) on
an OpenAFS directory, I get frequent "read(): No such file or directory"
and "read(): Input/output error" warnings.

Etc.
On closer inspection, it appears that files are being unlinked that are
still opened by the program. This should not be possible, right?
Is this a feature, a configuration problem (if so what?) or a problem in
the filesystem layer or OpenAFS code?
