The Process Engine is not running, therefore processes are not kicking off.
The following error appears in the BG log:
ProcessEngineThreadMonitor: Thread, Process Monitor (tenant=clarity) is not Alive. The Service running the ProcessEngine will need to be restarted.
The BG system logs shows that the JVM is not started.
Go to the Administration > Data Administration > Process Engines page to confirm that it is not in the 'Running' state.
If it is in the 'Cannot Determine Status', please contact the Support team to restart BG services.
