TMM can crash with segmentation fault when TMM drops packets on its internal loopback interface. TMM needs to update interface stats associated with the loopback interface when dropping packets on that interface. The interface stats object for loopback interface is not allocated yet. That results in segmentation fault.
Traffic disrupted while tmm restarts.
