Javascript 节点Redis命令将不运行？

这让我难以置信

我有一个BLPOP触发下面的源代码。当第一次触发源时，只会触发第一个Redis调用。。。第二个不会被触发，直到出现另一个pop并且再次运行源代码

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
null

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);
    });
});

问题是时间

我让blpop在同一个频道上，在blpop再次开始等待之前，只有一个命令被执行
