Re: Berkeley is good stuff!

 I would agree with you, and have only been using it from Oct 04 till now,
upgrading svn as I go. But their is some configuration mixture with BDB 4.2to
4.3 in this move to svn 1.2.0 that only one of our 7 repos did not handle
well, which was our largest 4+ GB.
Not saying it a Berkeley issue or an SVN issue, but seems to be some mix or
procedure in converting over in our case.

We chose the Berkeley path with the intention to use the hotbackup, which
helps for running two db back to back for recovery with less down time. At
the moment SVNADMIN can not seem to handle loading the dump file of this
size when restoring to BDB, but works just fine going to FSFS.
