Environment

Aria Operations 8.12.x
Aria Operations 8.14.x
Aria Operations 8.16.x

Cause

If a job is scheduled to run around the time of the start of time change, (typically around 2am the second Sunday of March and first Sunday of November) there may be an exception from SchedulerTemplate in analytics logs on pre-run email notifications. As a result the job execution process stops and jobs are triggered once there was no more email pre-run notifications sent.

Resolution

Solutions include:

• Upgrade to 8.17.x or later.
• Do not schedule any jobs on  the second Sunday of March and first Sunday of November
• Disable email notifications for any jobs which run on these days.
