Intermittent Events not triggering from Event Queue

[Rick Bakker]

Hello,

Does the background job check if any other instance of the background
job is running (eg the one from 6 minutes ago)? If so, what does it do
if it finds one?
If it kills the other one that could be a problem; if it doesn't kill
it then that could be a problem too, there could be some sort of
locking issue.

How does the program know when to create an event, it checks a table
for new entries?
