title: SVN can't get exclusive lock on file <repo>/db/txn-current-lock': Bad address
body: <p>Since an hour, I'm unable to commit to my svn repository. All repositories on my svn server are affected.</p>
  
  <p>Updating and checking out works fine. Committing yields the following error:</p>
  
  <pre>
  svn: Commit failed (details follow):
  svn: Can't get exclusive lock on file '/var/svn/repos/&lt;repo name&gt;/db/txn-current-lock': 
    Bad address
  </pre>
  
  <p>The problem started when I created a new repository with the name 'config', although I'm not sure this triggered the problems I'm encountering.</p>
  
  <p><code>svnadmin recover &lt;repo name&gt;</code> gives:</p>
  
  <p><code>svnadmin: Can't get exclusive lock on file '&lt;repo name&gt;/db/write-lock': Invalid argument</code></p>
  
  <p>Why does this locking problem occur?</p>
  
  <p>[edit]
  The server got worse, and started Segfaulting while trying to install updates. After rebooting again, the whole issue seems to be resolved... </p>
