Then something is badly fucked up in your system - it’s apparently stomping on memory when it shouldn’t - because the only time “isSSM()” is ever supposed to return True is if you’re using ‘source-specific multicast’, by creating “Groupsock” objects with a ‘source filter address’ parameter.  That doesn’t happen anywhere within our RTSP server code.

We’re definitely at that point now.
