Question

Tomcat随机停止接收请求并返回错误503 。

我正在更新Ubuntu 12.04 TLS上运行tomcat 7。

在apache错误日志中，您可以看到以下跟踪：

[Wed Mar 04 09:36:27 2015] [error] (111)Connection refused: proxy: HTTP: attempt to connect to 127.0.0.1:8080 (localhost) failed

[Wed Mar 04 09:36:27 2015] [error] ap_proxy_connect_backend disabling worker for (localhost)

任何tomcat日志文件（catalina）都没有错误跟踪：S

这不是由内存泄漏Head Space或Java Head Space引起的，因为我导致这些问题并且错误跟踪出现在日志文件中（此外，我查看了代码并且任何文件都没有system.exit()）

我很困惑，我无法理解发生了什么！
