发送5000个推送通知后，GCM超时和连接被拒绝

我需要在gcm服务上每秒发送500个推送通知 . 不幸的是，与chrome49不同，我必须为每个chrome50客户加密消息，加密密钥在请求标头中指明 . 在发送了5000条以上的消息后，我收到了从https://android.googleapis.com/gcm/send拒绝的超时和连接，并且它停止工作了一段时间，然后定期正常工作

发布在线程中运行的请求

try {
        String path = "https://android.googleapis.com/gcm/send";
        URI uri = new URIBuilder()
                .setPath(path)
                .build();
        HttpPost httpPost = new HttpPost(uri);
        httpPost.addHeader("Accept", "application/json");
        httpPost.addHeader("Content-Encoding", "aesgcm");
        httpPost.addHeader("Cache-Control", "no-cache");
        httpPost.addHeader("Connection", "Keep-Alive");
        httpPost.addHeader("Content-Type", "application/json");
        httpPost.addHeader("Authorization", "key=" + appKey);
        httpPost.addHeader("Encryption", encryptionHeader);
        httpPost.addHeader("Crypto-Key", cryptoKeyHeader);
        httpPost.setEntity(new StringEntity(jsonFromData));
        HttpResponse response = client.execute(httpPost);
        HttpEntity entity = response.getEntity();
        String responseString = EntityUtils.toString(entity).replace("%", "@");
        LOGGER.info(responseString);
    } catch (Exception e) {
        e.printStackTrace();
    }
