在我的java应用程序中，tomcat意外关闭。它只向网站显示“由于维护停机或容量问题，服务器暂时无法为您的请求提供服务。
请稍后再试。
'Apache / 2.2.17（Unix）mod_ssl / 2.2.17 OpenSSL / 0.9.8l DAV / 2 mod_jk / 1.2.31服务器在example.com端口8080'
此外，我检查了catalina日志，没有发现任何东西。我正在检查err_pid文件是否存在jvm错误，该错误表明存在错误，但我无法弄明白，我不是服务器架构师。
服务器详细信息：
os：Red Hat Linux
jdk：1.5.0_03
tomcat：5.5.9
ram：16 gb 这是err_pid.log文件。我想你将能够找到问题。err_pid.log

答案 0 :(得分：3)
在没有任何实际证据的情况下，我可以提供一些可能有用的观察结果。
您使用的是旧版Java。 Java 5于2004年发布，1.5.0_03是一个非常早期的补丁版本。公共补丁于2009年停止。
硬JVM崩溃（导致“err_pid”转储文件）通常可归因于第1 /第3本机代码库中的错误，偶尔也会归因于JVM错误。
通常可以通过查看“err_pid”文件获取有关发生的事情的线索。
我的建议是升级您的Java版本，至少升级到上一个公开发布的Java 5版本，最好是一直到Java 7.升级Tomcat可能是理所当然的......也是应用安全性的普遍闪电战补丁到机器。
如果您有必要的资金，您应该在测试/ UAT系统上尝试所有这些补救措施，然后再进行生产。 Java升级和Tomcat升级可能会引入问题，您不希望首先在生产服务器上体验它们。
其次，如果这是一次性事件，那么您可以做的最有成效的事情就是保存所有证据（日志文件，转储文件，配置等）并将问题放在一边。现在是YMMV，但总的来说，如果它再次出现，只值得研究这类问题。 （首先，在一次性事件中，很难知道您已确定原因并实施了正确的补救措施......）
