We have had a problem with out svn repo, it contains everything so is extremely important.
When we ran a dump we would get the error message
svnadmin: E200002: Serialized hash malformed
This is preventing us from performing a dump and moving our content, it also failed on a svn export.
We have found that one of the revisions is corrupt, is there anyway we can fix or repair a repository as we need to move it.
