Scheduled jobs gone awry

The next run time is not populated. The rule is still true. It stopped repeating around 2:17. This is the second time in 3 nights.

Rule:

The hub does DB backup and maintenance each night between 2 and 3 am, check what time the backup took place (Settings->Backup and Restore) the last few nights to see if that corresponds.

That is when it happened both times. @bobbyD Don't know if there is anything I can do to get more data. Should I e-mail support?

Happened on a different app today.
