下面是主函数，serverLink里是MPP编解码线程+socket控制编解码线程的开关。发送enable信号后，编解码线程启动。然后我发送了disable信号，编解码线程join，但是线程关闭后我看到top信息上该进程的%MEM仍然有6%。重复发送enable和disable信号后，每次%MEM都会上升，而且disable后没有打印mpp_meta: ~MppMetaService cleaning leaked metadata这些信息。直到我发送信号关闭整个进程，才会有mpp_meta: ~MppMetaService cleaning leaked metadata这些打印出来。
int main()
{
    serverLink();
    printf("close all\n");
    printf("ALL close\n");
}

MppBufferService cleaning leaked group解决了，编码少加了释放。但是加了释放后虽然没有再打印了，重复enable和disable物理内存MEM还是没释放掉，编解码线程重启MEM还是会比上一次线程启动时高
