tomcat 无故挂掉？

[GavinJ]

不同的服务器，同样一套代码，同样的 tomcat 配置。A 服务器正常 B 服务器每隔 1 天左右自动挂掉; tomcat 内存设置的也足够大了。访问用户没有几个，新部署的服务器。

你这已经是 tomcat 执行关闭时的日志了吧……

[nutting]

啥服务器，独立的还是云，虚拟机什么的

[defunct9]

开 ssh，让我上去看看

[xiaoyukid]

内存占用看看

[ytmsdy]

大概率是内存泄漏，导致内存爆掉。
看看把 tomcat 的内存设置的大一点，挂掉的时间间隔是否会增加。
如果增加了那就是内存泄漏的问题，

[logicr]

日志不是一直在说你的内存不足么

[seaswalker]

oom killer 杀掉了？

[KgM4gLtF0shViDH3]

@defunct9 每个这种问题下面都能看到你的这个回答，哈哈哈哈哈

[liwl]

开 ssh，让我上去看看

[szq8014]

mark, 你这日志不全

[FrailLove]

开 ssh，让我上去看看

[asd123456cxz]

是代码漏洞导致有内存泄漏的风险吗？字面上看是这样

[woscaizi]

感觉像是人工手动执行的 shutdown.sh

[1yndonn3u]

@defunct9 233333

[idamien]

这个应该是 tomcat 在部署 hs － service 时候有问题， 你可以重启，然后 tail － f 看看 catalina 的日志


然后 top 看看内存还有 cpu 使用情况 swap 情况

不行就接上 jmx 来看

[ixiaohei]

tomcat 8005 端口观点了么？

[ixiaohei]

关掉没有

[Charkey]

日志截取不全，看不到问题。

[defunct9]

哈哈，多了很多热心的群众，善莫大焉

[southsala]

是你机器内存足够大吧，给 tomcat 多分配点啊 大哥
