Our embedded application keep crashing VListinsertend after some time of operations. FreeRTOS code is generated using CubeMx.   What could be the possible issue ? 


FreeRTOS details

FreeRTOS 8.2 with heap 4 , Systick timer

osThreadDef(Task1, StartTask1, osPriorityRealtime, 0, 256);
osThreadDef(Task2, StartTask2, osPriorityHigh, 0, 196);
osThreadDef(Task3,StartTask3, osPriorityRealtime, 0, 256);
osThreadDef(Task4, StartTask4, osPriorityAboveNormal, 0, 196);


MicroController is STM32F303CC
256 Kbytes of Flash memory
40 Kbytes of SRAM


What should be the ideal CSTACK and HEAP size for the this kind of applications ?

Custom size cstack and Heap



Can anyone guide us in the right direction on how to find the right size of CSTACK and HEAP for the application ?
