Node.js工作器内存峰值使用请求时的错误R14＆amp; pkgcloud

这个让我感到困惑，因为它似乎随机发生。我有一个Node.js应用程序，可以传输推文（使用ntwitter），每秒向mongodb添加数百行。这部分总是工作正常，内存使用稳定。但最近我开始获取twitter头像的URL并将其保存到我们的rackspace CDN（使用“request”和“pkgcloud”模块）。我每20秒钟一次最多循环10次（但通常更少）并运行此代码：

request(idocs[ikey].tweet.user.profile_image_url.replace('_normal.', '_bigger.')).on('response', function(response) {
    console.log(response.request.path);
    avatars.push(path.basename(path.dirname(response.request.path)) + '/' + path.basename(response.request.path));
    var headers = {};
    if (response.headers && response.headers['content-type']) {
        headers['content-type'] = response.headers['content-type'];
    }
    if (response.headers && response.headers['content-length']) {
        headers['content-length'] = response.headers['content-length'];
    }
    response.headers = headers;
}).pipe(client.upload({
    container: process.env.RACKSPACE_CONTAINER,
    remote: path.basename(path.dirname(idocs[ikey].tweet.user.profile_image_url)) + '/'
        + path.basename(idocs[ikey].tweet.user.profile_image_url.replace('_normal.', '_bigger.'))
}));

一切都运行良好一段时间，但后来我在Nodetime中遇到了以下疯狂：

Memory spike!!!!

这是“heroku logs -p worker -t”的输出，当事情突然变得混乱时（请注意它是如何在大约600 MB的情况下正常运行然后在一个特定图像之后跃升至1GB以上 - 并且BTW所有图像都是标准推特尺寸为73x73，因此它不能是文件大小问题）：
