    Thanks for reporting this! The problem seems known and has
    to do with a deficiency in our multicast code WRT interface
    removal/re-insertion. It is on the to-do list of our networking
    gurus and hopefully will be dealt with RSN, after IP multicast
    code locking and cleanup are complete.
