SP1ML Standby mode current irregular

Im using SP1ML with the original firmware  in standby mode. the unit is going in and out of standby mode using a Timer 7  (4s awake) and RTC (4s asleep)

I am getting  the following current readings when toggling in and out of standby.  Every  now and again the unit draws 0.22mA as if  a clock or IO did disable correctly. i.e toggling every 4s:

<0.01mA (standby), 13.9mA (awake), <0.01mA,  13.9mA, <0.01mA, 13.9mA, 0.19mA, 13.9mA, 0.2mA, 13.9mA, <0.01mA, 13.9mA, <0.01mA, 13.9mA,

0.2mA, 13.9mA, <0.01mA, 13.9mA,<0.01mA, 13.9mA,<0.01mA, 13.9mA,<0.01mA, 13.9mA, 0.2mA,<0.01mA, 13.9mA,<0.01mA, 13.9mA, etc etc

 

I disable all the clocks and peripherals I enabled.

 

then call

 

     PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI);

 

Any Ideas why it would have this irregular current events every few random seconds?
