Description

A trigger that creates frequent events (such as ScheduledTrigger) with period less than the cool down period can starve all other triggers. This is because we execute triggers in the same order each time so if the scheduled trigger happens to be the first in the list then after every cool down period, the scheduled trigger can create another event and the cycle repeats.
