Fired when maintenance has begun.
Operations running when the event is fired should be terminated at the earliest opportunity. Scheduled operations (that are not scheduled through Atlassian APIs) should be disabled until maintenance is complete.
Failure to observe this may result in used database connections becoming invalidated, may prevent the product from starting its maintenance task or in the worst case may make the maintenance tasks (such as backup or database migration) complete unreliable.
