Both of them hung? Or did 'svnlook info' hang? Did you try doing what C.
Mike suggested in a previous email? Mainly:
"A trick I use to see how far along that process is, is to run '/usr/sbin/lsof
| log.00*'. During recovery, there are typically two logfiles opened -- the
youngest one, and the one currently being processed by recovery. When you
see those getting "closer together" (based on the numeric portions of their
names), you're generally close to being finished with the recovery."
It's important that you let the recover process finish before doing anything
else. And remember, you need to make sure that nothing is currently using
the repository when running 'svnadmin recover'.

I don't believe strace necessarily helped anything. It was hard to tell what
your exact order of operations was. If you happened to run 'svnlook info'
after a successful 'svnadmin recover', then there was no surprise that it
worked.

I don't think that TortoiseSVN necessarily had anything to do with this
problem.

Can you run 'svnadmin recover' on your repository and use C. Mike's suggestion
to see if it's making progress? You also need to make sure that you have the
correct permissions on your repository. I've seen some strange things happen
as a result of having mixed permissions on the repository. You need to make
sure that the apache user owns the entire repository.
