Answer 1

tomcat多次热部署之后是会outofmemory，不知道怎么解决，重启tomcat吧

Answer 2

吧tomcat启动时的内存参数设置的大一小,分陪的内存多一些

Answer 3

内存溢出一般都是session开启未关闭，占用内存引起的。

Answer 4

手动设置tomcat内存
tomcat默认内存为128
手动释放方法：
若用tomcat6.0,则
设置tomcat6w.exe在Java Options添加:
-XX:PermSize=256m
-XX:MaxPermSize=512m
如果你用的MyEclipse的话。。window--preferences--MyEclipse--application servers --tomcat--找到你的tomcat--jdk--vm arguments 设置一下：
-Xms256m -Xmx512m
-Dcom.sun.management.jmxremote=true

Answer 5

首选项里配置 -Xms256m -Xmx512m

Answer 6

代码确定没有问题吗，配置文件中的路径什么的都写全写对了吗？如果没问题就设置一下tomcat内存。先从代码上找原因.......
