That's exactly what I am seeing.
I'm testing some variations on how we delete. I think
I may have discovered something but I need to test some more.

Possibly a bug or glitch in the software....

        The only time I've seen database deadlock situations occur is when
I've run more
        than one delete filespace process at the same time.
