Problem stopping and restarting a Live555 RTSP client

C++

I am using a derivative of the Live555 testRTSPClient in an application. I am detecting stream failure by looking for missing frames. When I detect that the stream has been "silent" for too long, I need to close that stream and reopen it. I know the stream source is still working because other clients are still receiving. I am currently using only a single stream, but I left the code to handle multiple streams should I need it.

When I need to restart a stream, I call this function:

short StopAllRtspStreams(void)
{
    *env << "\n\n*** StopAllRtspStreams()\n";
    CaptureEnabled = false;
    if (initialized)
        StopExecThread();
    for (int i = 0; i < rtspClientCount; ++i)
    {
        if (rtspClients[i] != NULL)
        {
            *env << "shutting down " << *rtspClients[i] << "\n";
            shutdownStream(rtspClients[i]);
        }
        rtspClients[i] = NULL;
    }
    rtspClientCount = 0;
    // TODO anything else?
    return 0;
}

Then when restarting the stream, I call:

short StartRtspStream(char * rtspURL,
                      BufferPool_t * videoPool,
                      BufferPool_t * leftPool,
                      BufferPool_t * rightPool,
                      BUFFER_CAPTURE_CALLBACK_PROC callback)
{
    if (!initialized)
        StartExecThread();
    *env << "\n\n*** StartRtspStream(" << rtspURL << ", ...)\n";
    RTSPClient* rtspClient = ourRTSPClient::createNew(*env, rtspURL, RTSP_CLIENT_VERBOSITY_LEVEL, 0, videoPool, leftPool, rightPool, callback);

    if (rtspClient == NULL)
    {
        *env << "Failed to create a RTSP client for URL \"" << rtspURL << "\": " << env->getResultMsg() << "\n";

        return 0;
    }

    rtspClient->sendDescribeCommand(continueAfterDESCRIBE); 
    rtspClients[rtspClientCount] = rtspClient;
    ++rtspClientCount;
    return 1;
}

On the restart, the thing gets hung up waiting for the socket to connect:

*** StartRtspStream(rtsp://192.168.233.1/test, ...)
openConnection() entry
Opening connection to 192.168.233.1, port 554, socket 2148...
...connection pending (10035)

My code will detect that it didn't work, shut it down, and try to start it again. Over and over again. I'm guessing that I'm not shutting something down properly. I just can't figure out what.

Suggestions?
