    这是一个创建于 2040 天前的主题,其中的信息可能已经有所发展或是发生改变。

    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。

    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,

    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
