Question

使用ZMQ接收消息时，ZMQ总是出错的可能性。

我的开发环境：

zmq version: 4.1.4
server: centos7.0, 8cpu 2.0GHZ

代码如下：

{
zmq::context_t context(1);
zmq::socket_t socket(context, ZMQ_PULL);
socket.bind(m_config.m_strIPAndPort);

zmq::pollitem_t pollItems[]= {{socket,0,ZMQ_POLLIN,0}};
int MAX_POLLITEM_NUM = 1;

while ( !m_bStopThread )
{
    try
    {
        zmq::poll(pollItems, MAX_POLLITEM_NUM, -1);
        if( pollItems[0].revents & ZMQ_POLLIN )
        {
            zmq::message_t zmqMsg;
            bool bRes = socket.recv(&zmqMsg);
            if ( bRes )
            {
                pushMsg((const char *)zmqMsg.data(), zmqMsg.size());
            }
        }
    }
    catch (exception & e)
    {
        const char * pszError = e.what();
        string strErrMsg = "Error : receive cmd from client exception : " + string(pszError);
        qInfo(strErrMsg.c_str());
    }
}
}

GDB的堆栈信息：

在另一台具有更高cpu（例如3.2G）频率的服务器上运行它时，它可以正常工作。

我该怎么办？
