Couchbase网络错误16，node.js中的套接字声明失败

我有以下几天运行良好的node.js脚本，但现在却出现此错误：

I have the following node.js script which was running great a couple of days ago but now I get this error:

syd@HP-Notebook:~/Desktop$ node db.js
connected to database
{ [Error: Network error] code: 16 }
node: ../src/ioplugin.cc:496: virtual int Couchnode::IoOps::updateEvent(lcb_socket_t, void*, short int, void*, void (*)(lcb_socket_t, short int, void*)): Assertion `socket != __null' failed.
Aborted (core dumped)

，这是db.js的代码：

and here is the code for db.js:

var crypto = require('crypto');
var db = require('couchbase');
var couchBase = null;
var committed = 0;
var intervalID = null;

function strGen(len) {

    var text = '';
    var charset = "abcdefghijklmnopqrstuvwxyz";

    for (var i = 0; i < len; i++) {
        text += charset.charAt(Math.floor(Math.random() * charset.length));
    }

    return text;
}

function numGen(len) {

    var text = '';
    var charset = "0123456789";

    for (var i = 0; i < len; i++) {
        text += charset.charAt(Math.floor(Math.random() * charset.length));
    }

    return text;
}

function newLat() {
    var lat = Math.floor((Math.random() * 2)+1);
    if (lat == 1) return 37;
    return 38;
}

function createDocument() {

    var name = 'Test user #' + committed;
    var licensePlates = strGen(3).toUpperCase() +'-'+ numGen(4);
    var lat = parseFloat(newLat() + '.' + numGen(8));
    var lng = parseFloat('23.' + numGen(8))

    var timestamp = (new Date()).getTime().toString();
    var docKey =  crypto.createHash('md5').update(licensePlates + '-' + name).digest('hex');

    var docData = {
        '_id' : docKey,
        'name' : name,
        'lp' : licensePlates,
        'lat' : lat,
        'lng' : lng,
        'timestamp': timestamp 
    }

    //console.log(docKey);

    //console.log(docData);

    couchBase.set(docKey, JSON.stringify(docData), function(err){
        if (err) { 
            console.log(err); 
        } else if (committed < 1000) {
            committed++;
            console.log('#'+committed + ' - ' + ' Committed: ' + docKey);
        } else {
            clearInterval(intervalID);
            console.log('I\'m done!');
        }
    });

}

db.connect({
    'user':'taxi',
    'password':'taxi',
    'hosts':['127.0.0.1:8091'],
    'bucket':'taxi'
}, function(err, cb) {
    if (err) {
        console.log('TEST');
        console.log(err);
    } else {
        couchBase = cb;
        console.log('connected to database');
        intervalID = setInterval(function(){createDocument(null, null, null)}, 5);
    }
});

过去我没有任何问题。这是在我在ubuntu 12.04中安装php 5.4之后又返回到php 5.3之后发生的，因为我无法使用该版本的php来使该沙发床工作。仅供参考现在，couchbase可以正常工作，但不能与node一起工作。如您所见，与数据库的连接已建立，但set语句失败。任何信息，将不胜感激。

I didn't have any issues in the past. This occurred after I installed php 5.4 in ubuntu 12.04 and then returned to php 5.3 because I couldnt make couchbase work with that version of php. FYI php & couchbase work just fine at the moment, but not with node. As you can see the connection with the database is established but the set statement fails. Any info would be greatly appreciated.

更新

这是另一个脚本中的相同错误：

Here is the same error from another script:

syd@HP-Notebook:~/Desktop$ node test.js
Connection established!
Function: get
Network error

    at makeError (/home/syd/node_modules/couchbase/lib/bucket.js:578:18)

P.S。 memcache与node.js配合正常，我可以获取&组。 ouchnode / couchbase失败！

P.S. memcache is working fine with node.js I can get & set. couchnode/couchbase is failing!
