A new task is created in a demo lab as below:
/* Create task to handle uart gnss messges */
Task_Params_init(&taskParams);
taskParams.priority = 2;
taskParams.stackSize = 2*1024;
System_printf("gnss read task priority: %d \n", taskParams.priority);
Task_create(MmwDemo_gnssReadTask, &taskParams, NULL);
The program ran well for few hours, then terminated due to a arm.exc.Exception. The log is given as below:

It looks like a memory issue. Can you please give me any opinions about this error?
Thanks
