[midPoint] midPoint crash when validity scanner has too much objects

[Pascal PÉRICHON]

Hi,

We have 25000 student accounts to close (lifecycleState = archived) 
because date validTo is over.

Validity scanner have to work on 380000 objects and midpoint crash 
violently with an out of memory (heap size).

We increase the heap size until 42 Go but it crashed at 100000 objects.

midPoint seems to load all the objects in memory ?

Is there any workaround to avoid midpoint to crash (tasks to recompute 
and reconciliate accounts ?)

thanks
