My application uses 9 tasks – one of which is what I referr to as a general Mananagement task. It controls time related functions. This task is linked to the RTOS via a call to xQueueReceive with a timeout of 1. Within the the overall xQueueReceive loop — it may also call a vTaskDelay. This task has stopped running and my issue is I don’t know where it is. — most likely wating in a QueueReceive – which should return every tic as long as no higher priority task is running — which I know time is available since I can break into the idle task.. I can break on another task and walk it into the FreeRtos tsak manager — but I not sure the best way to see/identify where my task in question is and why it’s not running. Any debugging advice is welcome. Thanks. Joe

Have you tried running with FreeRTOS+Trace? (http://www.freertos.org/trace) You will be able to look in the time trace view to see what the task is blocked on. Alternatively, if you are using an IDE that has a StateViewer plug-in you will be able to see the handle of the object the task is blocked on. Which IDE are you using? Some have more sophisticated thread aware capabilities.
