Java Tomcat意外关闭，没有跟踪

首先，我必须说，我已经审查了所有相关的职位，但无法找到一个有效的解决办法

我让Tomcat 8.5.6在Centos 7上运行

我有一个在Tomcat（808080098443）上运行的API，它运行了很长一段时间而没有出现问题。上周我不得不创建一个新的API，问题开始了：Tomcat意外关闭，没有留下任何痕迹。我尝试将端口8007（转发到端口8443）用于新api。两个API都工作了，但Tomcat一直关闭。我尝试使用8081，但无法在其上创建连接

最后，我决定在端口8081上安装一个新的Tomcat实例，但无法使新的api在新的Tomcat（端口8081、8007和8444）上工作

我已经为第一个api正在运行的Tomcat禁用了关闭端口（-1），并停止了第二个Tomcat（因此我现在只有一个Tomcat在运行），并回滚了我所做的所有更改，但Tomcat一直在关闭

从Catalina.out日志中，我不能说太多（它没有说任何关于关闭的内容）。它只有启动结束和以下重启（每次我意识到它关闭时，我都必须订购）：

我是Tomcat和Centos的新手，但我已经为这方面的解决方案工作了很多天，但运气不好，我不知道为什么在部署新api时开始出现问题

我不确定这些信息是否足以进行分析，但我希望能得到任何帮助

谢谢。

谢谢大家的评论。我不知道为什么，但是有几个Tomcat进程处于打开状态。我重新启动了服务器，启动了Tomcat，现在似乎一切都正常，只有一个Tomcat进程

---

再次感谢

我怀疑我们能帮上多少忙，但是你有没有检查系统日志，看看操作系统是否正在杀死Tomcat？（谷歌搜索“oom killer”）检查是否生成了hs_err_pid*文件：用

catalina.sh run启动它，然后检查std上的输出，也许它会给你一个关于发生了什么的线索。
