title: How to fix "Failed to obtain lock" error in Endeca?
body: <p>Endeca does not seems to be popular here, anyway</p>
  
  <p><strong>The problem:</strong></p>
  
  <p>Accidentally kill a running base line update process, and the lock is left-over somewhere.</p>
  
  <p>I wish to find out where the left-over lock is, and to manually remove that.</p>
  
  <p>Not so useful message returned by the base line update script:</p>
  
  <pre>INFO: Checking definition from AppConfig.xml against existing EAC provisioning.
  INFO: Definition has not changed.
  INFO: Starting baseline update script.
  WARNING: Failed to obtain lock.
  
  ...ended</pre>
  
  <p>Alternatively, anyone can provide some links on endeca documentation (without login credential) will be helpful too.</p>
