subversion DB_RECOVERY

Something (?) has happened to my svn repository and I get the following error

[svn@snow /opt]$ svnadmin recover svn_certess
Acquiring exclusive lock on repository db.
Recovery is running, please stand by...svn: Berkeley DB error
svn: DB_RUNRECOVERY: Fatal error, run database recovery

I have had similar problem in the past - normally due to permissions. I
ensured the permissions are ok in the db directory and am sure I am running
as the correct subversion user for administering the repository.

Strangely enough I was able to update a working copy as a normal user. I
admit to using an old version of subversion (5972 from the repository).

Where do I go from here ?

Thanks,
        Mark
