Wrong mailing list. I guess that you want to reach users@ Apache Subversion
<http://subversion.apache.org/mailing-lists.html>, not users@ TortoiseSVN.

Anyway, it seems to me that rep-cache became corrupted in this repository.
If that's the case, this problem is easy to solve. First and foremost, try
to repair the repository this way:

   1. Rename the file "PATH-TO-AFFECTED-REPOSITORY\db\rep-cache.db" to "rep-
   cache.db-corrupted".
   2. Restart the server.

Any errors this time?

BTW, the size of your repository has nothing to do with keeping your SVN
server or clients up to date. You should have no problems to update from
1.8.10 to 1.8.16.
