The fact that the scheduler service is not running does not prevent the FIM custom workflow from firing the nominated Event Broker operation list.
While this arguably makes sense when you consider that this is the only non-polling interface for EvB, it was still unexpected because it would be fair to say that most FIM administrators would expect that stopping the scheduler should disable all interaction with FIM.
This issue probably falls into the "traps for young players" category, as there is an easy work-around as long as you remember to ALSO disable the corresponding FIM MA (inbound) operation list. My point is that I expect 9 out of 10 admins will be a victim of this oversight unless this "feature" is not spelled out clearly somehow.
Unless this feature was unintentional, then we probably need to talk this one through to decide what's best to do here ... agreed?
