I've been working with the OpenAFS fileserver on a NetBSD machine for
a while, and been able to do some reasonable speeds on various benchmarks
I've been using.  Just before deciding to put it into production, I
decided to run a few additional tests, and found a few volunteers.
They're very good volunteers, they made it crash.

While copying pkgsrc to an afs volume on my server (from an afs
volume on a different server):
(cp -r /afs/ .)

I'm running 2.0_BETA for these tests.

(BTW, if anyone is interested in OpenAFS, I'd like to get the client
and server working on NetBSD, and I could use help.  There's a mailing list, although of the 6 posts ever,
3 are mine.)
