Awake again now... Yes, the lines in 'module memory' output identified by a hex number are ones where the scan through allocated memory blocks finds blocks owned by a task with that TCB address but that uxTaskGetSystemState() does not include a task with that TCB address. The code keeps a map of TCB address to name so that it is possible to show by name the memory belonging to tasks that have exited, but that map only gets populated two ways: - When 'module memory' or 'module tasks' is run - When a task is created with the TaskBase class - By calling AddTaskToMap() after creating a task, as I added for the main and Housekeeping tasks. Michael has used TaskBase when creating a command task, so that case would be covered. There might be some places where we create other tasks not using TaskBase where a call to AddTaskToMap() could be added. But for tasks created on our behalf by system code, those won't be covered unless we can put the AddTaskToMap() call in our code that causes the task to be created. -- Steve On Mon, 19 Mar 2018, Mark Webb-Johnson wrote:
These are tasks that were started and then exited (leaving memory unfreed)?

I see there are a couple of tasks that allocated memory but did not free it. These are the tasks identified by TCB address in the module memory listing:
