核心代码如下

m_bRunning = true;
    // first let's increase the limit of open files
	int maxconn = 100000;
	struct rlimit srl;
	srl.rlim_cur = maxconn + 10;
	srl.rlim_max = maxconn + 10;
	if (setrlimit(RLIMIT_NOFILE, &srl) < 0)
	{
		LOG4CXX_FATAL(logger_, "Cannot set RLimit!");
		exit(1);
	}
	epfd = epoll_create(maxconn);

    if (epfd < 0)
    {
        LOG4CXX_FATAL(logger_, "epoll_create error!");
        exit(1);
    }

    // Now let's ignore broken pipes
    struct sigaction sa;
    memset(&sa, 0, sizeof (sa));
    sa.sa_handler = SIG_IGN;
    if (sigaction(SIGPIPE, &sa, NULL) < 0)
    {
        LOG4CXX_WARN(logger_, "Error ignoring SIGPIPE!");
    }

    if (initSockets() < 0)
    {
        exit(1);
    }

    struct epoll_event ev, evs[MAX_EVENTS];
    LOG4CXX_INFO(logger_, "Nethandler started.");
    for (; ; )
    {
		if (!m_bRunning)
		{
			break;
		}
        int count = epoll_wait(epfd, evs, MAX_EVENTS, 10);
        if (count < 0)
