tomcat部署项目经常自动关闭问题

各位大神,您们好!
小弟最近遇到一个难解的问题,希望大神指点一二。
项目描述:
1、项目中框架用的是springmvc+mybatis,中间加了elasticsearch和rabbitmq,数据库用的是mysql,连接池用的是阿里的druid
2、项目是分开部署的,共用了5个tomcat,之前开发是单个单个启动调试所以没发现问题。但现在找了台服务器一起部署,然后。。。就经常会全挂。
下面是某台tomcat挂后最后打印的部分日志。还请大神能提出解决方案!成分感谢!

挂之前没有错误日志吗?还有你说项目是分开部署的,共用了5个tomcat,是做了集群?还是这么个意思?
如果是多台机器,不同的web系统应该不会相互影响的
