KE04 Lockup reset

Dear all, I have KE04Z8VWJ4 processor.
I used about 100 pieces on the production line without any problem.
With the new lot some microcontrollers reset after a few seconds.
Using the flash on an output I checked the contents of the SIM_SRSID register and verified that the cause is LOCKUP.
I ask for your help to understand the possible cause of this reset.
- Could it be caused by software error?
