PhantomJS 在 150-180 个 url 后崩溃

Question

到目前为止，我的脚本工作正常，按顺序逐行加载文本文件中的每个页面（page.open 是异步的，页面对象是全局的 = 覆盖新请求，这是一个大clusterfuck 运行同时使用多个 page.open()），匹配特定域的每个请求并从中打印 JSON 值。

但是，如果我使用包含超过 150 个链接的 .txt 文件，它每次都会崩溃，大多数情况下没有错误消息，也没有像这样的崩溃转储：

PhantomJS has crashed. Please read the crash reporting guide at http://phantomjs.org/crash-reporting.html and file a bug report at https://github.com/ariya/phantomjs/issues/new. Unfortunately, no crash dump is available. (Is %TEMP% (C:\Users\XXX\AppData\Local\Temp) a directory you cannot write?)

如果我运行多次，我可以很容易地重现它，无论我是一次还是一个接一个地重现。我怎样才能防止崩溃？如果 Phantom 无法处理，我的脚本就没用了。

但有时我会得到一个故障转储：

在极少数情况下，我什至会收到一条错误消息，Process Explorer 说该进程一次最多有 21 个线程

QThread::start: Failed to create thread ()

var stream = fs.open('500sitemap.txt', 'r');

var hasonLoadFinished = Array();

function handle_page(line) {
var page = webPage.create();
page.settings.loadImages = false;
page.open(line, function() {});

page.onResourceRequested = function(requestData, request) {
    var match = requestData.url.match(/example.de\/ac/g)
    if (match != null) {
        hasFound[line] = true;

        }
        i++;
        setTimeout(page.close, 200);
        nextPage();
    }
}
};

function nextPage() {
var line = stream.readLine();
if (!line) {
    end = Date.now();
    console.log("");
    console.log(((end - start) / 1000) + " Sekunden");
    phantom.exit(0);
}
hasFound[line] = false;
hasonLoadFinished[line] = false;
handle_page(line);
}

start = Date.now();
nextPage();

/edit 在 3836 个链接后与 1.9.8 崩溃....返回开始......

看来是2.0版本的问题。出于挫败感测试了 1.9.8 - 它有效，使用的 RAM 减少了 60%，1000 个 Urls 没有崩溃。

github 的崩溃报告已完成，真是令人欣慰，它有效。
