This might have something to do with it.

The code looks like this message gets printed when SDP
calls sdp_path_info_distroy(). Question is, why is it tearing 
down the connection ?

/*
 * sdp_link_sweep - periodic path information cleanup function
 */
static void sdp_link_sweep(void *data)
{
        struct sdp_path_info *info;
        struct sdp_path_info *sweep;

        sweep = info_list;
        while (sweep) {
                info  = sweep;
                sweep = sweep->next;

                if (jiffies > (info->use + SDP_LINK_INFO_TIMEOUT)) {
                        sdp_dbg_ctrl(NULL,
                                     "info delete <%d.%d.%d.%d> <%lu:%lu>",
                                     info->dst & 0x000000ff,
                                     (info->dst & 0x0000ff00) >> 8,
                                     (info->dst & 0x00ff0000) >> 16,
                                     (info->dst & 0xff000000) >> 24,
                                     jiffies, info->use);

                        sdp_path_info_destroy(info, -ETIMEDOUT);
                }
        }
