Tomcat隨機停止接收請求並回傳錯誤503。
我在更新的 Ubuntu 12.04 TLS 上運行 tomcat 7。
在 apache 錯誤日誌中，您可以看到以下追蹤：
[Wed Mar 04 09:36:27 2015] [error] (111)Connection refused: proxy: HTTP: attempt to connect to 127.0.0.1:8080 (localhost) failed

任何 tomcat 日誌檔 (catalina) 中都沒有錯誤痕跡：S
這不是由內存洩漏Head Space 或Java Head Space 引起的，因為我導致了這些問題並且錯誤跟踪出現在日誌文件中（此外，我查看了代碼，並且任何文件上都沒有system.exit() :P） 。
我很困惑，不明白發生了什麼，提前謝謝！
