If I remember correctly Subversion 1.1 used Berkeley DB (BDB) for various purposes - for example the repository format might be BDB.
BDB relied upon file locking to enforce data consistency. As I mentioned not all implementations of NFS servers fully implement file locking - this is why you are receiving these errors. My recommendation is that you should migrate to a newer version of Subversion /and/ to a service based serving of the Subversion data rather than using file:// based access to the repository.

But recently when I was trying to commit my changes (svn commit -m "DeFrac final changes"), from my local working copy, I got the following error message: svn: Commit failed (details follow): svn: Unable to open an ra_local session to URL svn: Unable to open repository 'file:///ENGDATA/DeFRAC/defracdev/repository/maintv2/trunk<file:///\\ENGDATA\DeFRAC\defracdev\repository\maintv2\trunk>' svn: Error opening db lockfile svn: Can't get shared lock on file '/ENGDATA/DeFRAC/defracdev/repository/locks/db.lock': No locks available I tried to issue the recover subcommand (svnadmin recover /altroot/ENGDATA/DeFRAC/defracdev/repository), but still I received the following message: Repository lock acquired. Please wait; recovering the repository may take some time... Recovery completed. svn: Error opening db lockfile svn: Can't get shared lock on file '/altroot/ENGDATA/DeFRAC/defracdev/repository/locks/db.lock': No locks available I would appreciate your help.
