title: svn: database is locked, executing statement 'RELEASE s0'
body: <p>I keep getting the error listed blow in attempting a merge from a private branch:</p>
  
  <blockquote>
    <p>database is locked, executing statement 'RELEASE   s0'</p>
  </blockquote>
  
  <p>I run collabnet subversion edge server: 1.7.5-3220.94</p>
  
  <p>I run the tortoise svn client: TortoiseSVN 1.7.7, Build 22907 - 64 Bit , 2012/05/15 12:16:05</p>
  
  <p>Can anyone please point me to what's causing this, and how to resolve this. The references on the Web suggest some process is using the sqlite backend. The generic "Release lock" action from svn client contextual menu doesn't seem to help?</p>
