没啊 两个tomcat的catalina日志什么错都没 Free memory: 12.18 MB Total memory: 37.23 MB Max memory: 63.56 MB刚才看了一下另一个tomcat的运行状态 最大内存是默认的 就60多M
一般就是内存问题，如果tomcat的各项参数没有问题那么你就需要检查代码了
内存，还有是不是服务器重启了，将tomcat服务设置为自动启动
现在两个tomcat set JAVA_OPTS=-Xms256m -Xmx512m 设置jvm 初始和最大内存都是startup.bat启动的 要注册成服务启动码？

在启动参数加这个，可以在你内存溢出的时候dump下来，
然后分析大概是什么造成的
