节点Redis命令不会运行？

Question

这让我难以置信。

我有触发下面的下面的源代码BLPOP。当第一次触发源时，只有第一个Redis调用被触发......第二个不会被触发，直到有另一个弹出并且源代码再次运行？

null 
DEBUG - 8621 - Sat Feb 18 2017 20:47:53 GMT-0600 (CST) - 5 totalConnections 2000 
null 
DEBUG - 8621 - Sat Feb 18 2017 20:47:54 GMT-0600 (CST) - 5 expectedConnections 500

const expectedConnectionsKey = ['test', id, 'expectedConnections'].join(':'); 
const totalConnectionsKey = ['test', id, 'connections'].join(':'); 
watcher.client.incrby(totalConnectionsKey, connections, (error, totalConnections) => { 
    console.log(error); 
    log.debug(id, 'totalConnections', totalConnections); 
    watcher.client.get(expectedConnectionsKey, (error, expectedConnections) => { 
     console.log(error); 
     log.debug(id, 'expectedConnections', expectedConnections); 
    }); 
});

问题是具有定时...

我曾在同一信道上的BLPOP，只有其中一个命令之前BLPOP开始等待再次得到了执行。
