Can you tell us the contents of those three files please? That will
show us which format of the backend you're using (you've mentioned svn
1.6.16, and I'm not sure if you have 'svnadmin upgrade'd to the latest

I have seen several hotcopy-fixes mentioned for the upcoming 1.9
release [1]. Maybe, as a test, you can try if the same problem still
happens with 1.9-beta1?

[1] search for 'hotcopy' in
http://svn.apache.org/repos/asf/subversion/trunk/CHANGES
