This really looks like the refresh bug that was corrected in 1.2.4.
Did this happen with OpenAFS 1.2.3 or the 1.2.4 release candidate?

Ok, let me rephrase: can you show me the actual steps that cause
the problem?  Find the portion of the bonnie tests and cut-and-paste
just that test that causes the failure.  For example:

        mkdir ...
        touch ..
        rm ...
        rmdir .. <- crashes

I'd like to see a concise "this will cause the crash" process.
I don't have access to "bonnie++".

Thanks.  That would be useful.
