The root cause of the issue was that th= e interrupt handler was cleaning up resources such as the ethdev and eventd= ev ports, and once the interrupt handler would return, that thread would co= ntinue working as an eventdev worker, and dereference the memory which just= had free() called on it. Fixed by moving the cleanup code from the interrupt handler to the cleanup = stage of main(), which the master thread will execute once it has returned = from its worker() functionality.
