    Human Task Email Notification Issue in JBPM 5.3

    Shiva Kumar Balasani Newbie

      Users suddenly stopped receiving Human Task related email Notifications. When I checked the SessionInfo table no new entries are getting created in the table. Not sure what triggered this issue. I checked the logs and found the following error message in the logs. Can anyone suggest how I can resolve this issue?
