TMM crash on stop or restart.


TMM crash generates a core file. However, there is no impact on traffic as the device is already in a bad state before the crash.


1. Put the virtio NIC in a bad state while TMM is running (for example, detach the NIC from the host). 2. Run the following command: bigstart stop tmm



Fix Information

TMM does not crash on stop/restart regardless of NICs state.
