can't recover svn repository

Hello

start:

$ svn log svn://myserver/myproject
svn: Reference to non-existent node '2mnj.2db.814' in filesystem
'/var/svn/repos/db'

$ svnadmin verify -r 9699 /var/svn/repos
svnadmin: Reference to non-existent node '2mnj.2db.814' in filesystem
'/var/svn/repos/db'

$ svnadmin recover /var/svn/repos
Repository lock acquired.
Please wait; recovering the repository may take some time...

Recovery completed.
The latest repos revision is 12171.

goto start;

I am using subversion 1.5.6 as debian package and db4.6 as a backend. Any hint
how to fix it?

Thanks in advance
Bestregards
