Python windows上运行的CherryPy服务器出现随机锁定错误

我正在使用基于文件的会话运行CherryPy服务器。当我在mac上运行服务器时，它工作正常，但当我在windows机器上运行时，我遇到了问题

我有一个web应用程序，它在页面加载时向服务器发出许多GET请求（~50）。通常在一个或多个请求中，我会在服务器上收到下面的错误消息。每次的GET请求都不相同，这似乎是随机的。有时它加载时没有任何问题

你知道为什么会发生这种情况，以及我如何解决它吗？

我只能说，在一定程度的并发性下，你的Mac可能也会出现问题。如前所述，CherryPy文件会话锁定已中断。不难假设Windows锁定也存在高并发性问题。对于*尼克斯来说，它是固定的，但它不会很快出现。同时，您可以切换到memcached内置后端或。谢谢。我想使用文件会话的唯一原因是，如果服务器重新启动，我就不会忘记哪些会话处于活动状态。我将尝试看看是否有办法定期将活动会话列表保存到文件中，然后在加载时将这些会话放入内存。Redis默认情况下是持久的，因此您可以按原样使用。但是请注意，如果运行多个CherryPy实例，则需要在Redis中实现会话锁定，或者确保一致地将用户路由到实例。
