QlikSense - Scheduler terminates on startup with Unexpected exception

It has been reported that in the version 3.2 of QlikSense we have unfortunately an unwanted strange behavior.
 
Meaning that we can see the Scheduler Service crashing on startup.
The error can be recognized by inspecting the Scheduler Service trace log, searching for this line:
  
“System.Scheduler.Scheduler.Core.Utility.SystemInformationProvider 8          704664c5-1aca-40b8-8570-8b294d95d10d     DOMAIN\Administrator          Unexpected exception when checking Repository responsiveness/validating license       An item with the same key has already been added.”
 
Followed up by an : “System.Scheduler.Scheduler.Main   8       fa6fb50e-cc0c-4a61-be63-1b9c0cb53c9c    DOMAIN\Administrator Startup sequence failed. Shutting down to avoid any inconsistent state. Please try to restart the Scheduler.”

Under some special circumstances, the scheduler terminates at startup

The issue is fixed in Qlik Sense 3.2.4 and later.
This is caused by the repository database table "ExecutionSessions" containing rows that have ReloadTask_ID field duplicated.
