BigIP - Tomcat 8連接拒絕從Tomcat 6升級6

Tomcat開始監聽端口並且應用程序也被部署，但是當我訪問URL時，我得到連接拒絕錯誤。 BigIP無法識別服務器上由tomcat 8打開的端口是否存在任何問題？BigIP - Tomcat 8連接拒絕從Tomcat 6升級6

雖然當我恢復到tomcat 6（啓動和停止它），然後再次嘗試與tomcat 8它有時開始接收連接是奇怪的，我無法找到原因。可能是什麼問題？

添加控制檯/日誌文件輸出的相關部分。你認爲「寧靜的終點變得無法到達」是什麼意思？可能是因爲你的WebApplication不能啓動？沒有日誌文件/控制檯輸出很難說。 – andih

感謝您的回覆和ih。請忽略寧靜的端點。我編輯了這個問題。請讓我知道您的意見 –

在這種情況下，您可以使用端口9030訪問應用程序？日誌文件/控制檯輸出在不能時如何顯示？ – andih

每個傳入請求要求針對該請求的持續時間的線程。如果收到的併發請求數多於當前可用請求處理線程可處理的請求數，則會創建額外的線程，直至配置的最大值（maxThreads屬性的值）。如果還有更多的併發請求被接收到，它們被堆疊在由連接器創建的服務器套接字中，直到配置的最大值（acceptCount屬性的值）。任何進一步的同時請求都會收到「連接被拒絕」錯誤，直到資源可用於處理它們。

多參考在https://tomcat.apache.org/tomcat-8.0-doc/config/http.html

感謝Omkar，但在我的應用程序MaxThreads設置爲http.port.maxThreads = 100，我甚至無法訪問應用程序。因此，甚至不會創建一個線程 –
