Do scheduled jobs wait before running again?

[davidmcdonald]

Lets say I've created a Scheduled Script Execution job, that runs every 30 seconds. If an execution is taking longer than 30 seconds, with the next job wait for the last one to complete, or run over the top of the last one?

It won't, a repeat job is still running, it will not start the schedule.

There can not be two instances of the same scheduled job running at the same time.

i.e. OOB Email Reader waits, so would the other scheduled jobs.

[vab_13]

if a job is triggered by an event, then it is possible to overlap,

e.g event processor job is a repeat job, it won't run more than 2 on the same node if it got stuck
