      Description

      We have a Memory error in the course competencies page:

      PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 7 bytes) in /app/apache2/htdocs/moodle/lib/dml/mysqli_native_moodle_database.php on line 1188

      The error is caused by a slow sql querie in the method get_least_proficient_competencies_for_course() in file:
      /app/apache2/htdocs/moodle/competency/classes/user_competency_course.php

      We are not able to reproduce easely for the moment. Some course have the problem, other, not.
      Also, we have a huge Moodle environnement with many competencies. The tested course have no competencies.
