If you can do that, I would suggest the following:
- Stop all accesses to the repository, also stop BDB.
- Put your old BDB (is it 4.2?) in place.
- Move the repository aside, e.g. with 'mv -iv REPOS REPOS.old'
- To avoid issues with dump-files getting too big, use the attached
'dumprev' script (after modifying it to your needs) to create
incremental dumps from REPOS.old.
If that fails, *shrug* well, stop here and go home.
You might feel the urge to reach for an axe, but please resist.
- If that worked: switch (back) to BDB 4.3
- create a new (empty) repository that has the name of the old one.
- Use the attached 'loadrev' script (after modifying it to your needs)
to load the incremental dumps into the new repository.
- After that finished successfully, restart BDB and all access methods.
These scripts are tested just for the dumping from an existing backup
repository (created with 'svnadmin hotcopy ...') and loading into a
new repository under linux and work fine. I wrote 'dumprev' some time
ago and 'loadrev' maybe half an hour ago and did one test with it.
If you have any questions about it, just ask. :-)
But I use FSFS, so I cannot speak for BDB repositories, esp. ones
that already seem damaged.

Hmm, then maybe you might want to add 'sleep 1' into the loop that
loads the incremental dumpfiles, so that svn has 1s after each load
operation to think about what it just did. ;-)
You might also add 'echo -n "."' after the 'svn dump ...' inside the
loop in 'dumprev' so that you see that is still running. I didn't need
that because we only had 56 revnums in our
