RTOS/TMS320C6678: Getting real time heap stats for HeapBufMP

Part Number:TMS320C6678

Tool/software: TI-RTOS

Hi, 

I currently have a program that sends data over a messageQ from core0 to core1 for 100 iterations (to put it simply), however before the 100 iterations are up i run out of blocks in the heap created in the shared region as core0 is sending the messages quicker than core1 can receive the message and free the buffer, a solution i had thought of was to count how much of the heap had been allocated and to only send data when this was below a certain number. Currently i am trying to use the Memory_getStats() function for this and whilst i am getting usable outputs in another queue, the queue that i want to analyse always outputs that 0 memory has been allocated even when the program fails to complete the run due to a lack of heap blocks. Is there a reason it works in one queue and not the other? they both share the same heap space so it is not a wrong handle issue. Below is the function in which messages are sent to core1 with the Memory_getStats function included, i have also set HeapBufMP.trackAllocs  = true in the config.

void send(char* name, float* data){

    Task_sleep(1);
    //Open Queue created by other core, loop until found
    do {
         status = MessageQ_open(name, &QueueId[id]);
         if (status < 0){
             Task_sleep(1);
             }
     }while (status < 0);

     //allocate message to heap
     msg = MessageQ_alloc(HEAPID, sizeof(myMsg));
     if (msg == NULL){
                 System_abort("MessageQ_alloc failed\n");
             }
     ((myMsg*)msg)->message = data[0];

     //put message in messageQ
     status = MessageQ_put(QueueId[id], msg);
     
     xdc_runtime_Memory_Stats* stats;
     Memory_getStats((IHeap_Handle)heapHandle, stats);
     System_printf("max alloc %x\n", stats->totalSize);
     System_printf("alloc remaining %x\n", stats->totalFreeSize);
     
     id++;
}
