Hi,  
When I call vTaskDelete(NULL) to suicide task, it passes to ‘delete’ status (i can look it by vTaskList()) but allocated memory is not freed (like i’d want).  
Someone can help me?

I am using:  
heap3  
and  
#define INCLUDE\_vTaskPrioritySet&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1  
#define INCLUDE\_uxTaskPriorityGet&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1  
#define INCLUDE\_vTaskDelete&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1  
#define INCLUDE\_vTaskCleanUpResources&nbsp;&nbsp;&nbsp; 1  
#define INCLUDE\_vTaskSuspend&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1  
#define INCLUDE\_vTaskDelayUntil&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1  
#define INCLUDE\_vTaskDelay&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1  
#define INCLUDE\_xTaskGetCurrentTaskHandle 1

Bye.

Thank you a lot.  
Your hint reminded me that I used a while(1) in the idle task =\> prvCheckTasksWaitingTermination never was called.

Thanks again.
