Tomcat无缘无故停止

最近遇到个问题，有个线上的tomcat总是运行一会儿就自动停止了，莫名其妙的没有任何报错。

在网上搜了一下，发现是跟这篇文章同样的一个原因

原来罪魁祸首就是启动脚本里的一个 tail -f

tail -f shows the logs continuously so the script doesn't finish it's execution automatically. When the ssh connection timed out while my script was still running,shell killed it WITH IT'S CHILD PROCESSES - a Tomcat server among others and that was the whole problem. 

把tail -f去掉，问题解决。
