SYMPTOM:
Scheduled jobs show a status of "Cancelled" in the job monitor in Strategy Developer 9.x but the jobs still go to completion. For example, a scheduled cache update job will start and execute but then the status of the job changes to "cancelled" in the job monitor. However, users notice that the cache is in fact updated indicating that the job ran through to completion.
Additionally, if a notification email is set to be sent upon the scheduled job's completion or failure, users note that an email is not sent.
CAUSE:
A possible cause is if statistics are enabled and while the Intelligence Server is actively writing data to the statistics database, the database may be full which causes a backup of the Intelligence Server jobs resulting in the jobs not executing to completion.
ACTION:
Increase the statistics database size or purge statistics from the database to free up space. After doing so, restart the Intelligence Server and scheduled jobs should run to completion.
