NAS - AutoOperator set to On Every Interval

Some auto operator profiles set to Action type - On Every Interval with a time specified.
And this works well. It reprocesses current alarms on the interval specified as expected.
However  if   NAS probe restarts, all the alarms are processed again. Whether or not the interval time is due. Which means a flood of alarms being processed on a NAS restart. Alarms processed On Arrival are not - reprocessed (obviously) on a NAS restart.
Is there a way to tell the NAS to not do this? Not to reset the interval time?
Or is there another method to re-process existing alarms on a given interval, without the flood / reset of interval on a NAS probe restart?
NAS 8.42 (UIM 8.51) 
Primary Hub Windows 2008 R2. 
Robot 7.80HF21 

Note:  It  is also observed with nas hotfix 8.56. 

Resolution: (8.56T1 ) should be compatible with UIM 8.56. 

The 8.56T1 build is on top of nas 8.56 available on hotfix link 
Additional Information:
To reproduce: 
- Create  AO profile with: action type: EMAIL, Action mode: On every interval 5min, Severity level: Critical, Message string: *Test*, 
- Send test alarm: Test 
- It should see the email come in at 5 min intervals.
- Then deactivate/activate nas in the middle of the next interval, 
an email will be sent right away once nas is activated.
