升级后 DNN 事件日志充满 2sxc 错误，这可能是什么原因造成的？

升级到 2sxc 17.9 后，我们看到事件日志充满以下错误：

也许相关，当客户保存新闻文章时，他们会收到错误“与服务器对话时出错（状态 0）”。不过这篇文章似乎被保存了。

看起来这种情况也发生在其他 dnn 安装上，以及我们升级到 2sxc 17.9 的情况。当我们编辑或添加新闻文章，然后单击“保存”按钮时，它会对实体选择器 api 进行 1 次或多次调用，这些调用会被中止，因为保存操作会在返回响应之前关闭请求。

您可能正在 IIS 中运行 2 个或更多共享同一个应用程序池的 DNN 实例，请尝试分离应用程序池
