  Configuration Issues: Incorrect configuration of the data source or the InfoProvider can lead to locking problems.

  Reconfigure: Review the configuration of the data source or InfoProvider to ensure that everything is set up correctly.
  Database Check: Check the database for any issues, such as deadlocks or connection problems. You may need to work with your database administrator to resolve these.
