That means that something is forming the MGID improperly (from the IPmc
address 224.0.0.9). Specifically, the MGID must start with 0xFF in the
first byte. Is the MGID displayed slightly earlier in the log ? If no,
can you run with -V and it should be there to see what the SM is seeing
for the invalid MGID.
