Android 错误： java.net.SocketException： Socket 已关闭

我看到这个错误每周在我的崩溃日志中出现数百次，但我已经花了几个星期试图追逐错误，没有任何成功。我无法在任何设备上重现它。下面是堆栈跟踪：

这是错误来自的代码块...崩溃发生的确切位置是：HttpResponse response = httpclient.execute(httppost);

 public static HttpPost postData(String URL, final List<NameValuePair> params, final Handler handler) {
        // Create a new HttpClient and Post Header
        //android.util.Log.d("Utilities", "Called postData");
        final HttpClient httpclient = new DefaultHttpClient();
        //httpclient.
        final HttpPost httppost = new HttpPost(URL);
        final Message msg = new Message();
        final Bundle dataBundle = new Bundle();
        final ByteArrayOutputStream out = new ByteArrayOutputStream();

        new Thread(){
            @Override
            public void run(){
                String error = "";
                String data = "";
                try {
                    httppost.setEntity(new UrlEncodedFormEntity(params));
                    HttpResponse response = httpclient.execute(httppost);
                    StatusLine statusLine = response.getStatusLine();
                    if(statusLine.getStatusCode() == HttpStatus.SC_OK){
                        response.getEntity().writeTo(out);
                        out.close();
                        data = out.toString();
                    } else{
                        error = EntityUtils.toString(response.getEntity());
                    }
                } catch (ClientProtocolException e) {
                    AirbrakeNotifier.notify(e);
                    error = e.toString();
                } catch (IOException e) {
                    AirbrakeNotifier.notify(e);
                    error = e.toString();
                } catch (Exception ex) {
                    AirbrakeNotifier.notify(ex);
                    error = ex.toString();
                }
                dataBundle.putString("error", error);
                dataBundle.putString("data", data);
                msg.setData(dataBundle);
                handler.dispatchMessage(msg);
            }
        }.start();
        return httppost;
    }

任何帮助最终弄清楚这一点，非常感谢！
