I know somebody has mentioned it before. I'll mention it again. You need
to recover the database. The exact syntax to recover is either in the
mailing list archive or in the FAQ someplace.

The short term solution for SVN, and I'm not sure that ra_svn changes
this at all (I haven't read the code) is to add BDB lock timeouts. The
trouble being how long should the timeout be? I'm going to take a stab
and say 2min should definitely be more than long enough, or your
Subversion server is too overloaded in the first place.

After we do that if the children still hang then we'll start needing
more reproducible test cases.

Having said all of the above: You're using Subversion in production? Are
you nuts? We haven't released yet. ;)
