对 Android 上使用 Jetty 引擎托管的 Ktor 的请求超时

Question

我在带有 Jetty 引擎的 Android 设备上托管 ktor 服务器，并且请求不一致地需要 30 秒才能超时，并出现

java.util.concurrent.TimeoutException: Idle timeout expired

异常。如果发生这种情况，响应仍然会在 30 秒结束后正确发送给 Postman。有时可以通过重新启动设备来解决该问题，但这作为解决方案是不一致的，并且不能真正解决问题。如果问题没有发生，请求最多需要 500 毫秒才能响应。

这是

Selector sun.nio.ch. PollSelectorImpl@842116 waiting with 1 keys

线之后发生 30 秒差异的日志。
