tomcat 内存溢出问题

[老程序员]

大家好!!
我在SERVER.xml里多加几个<Host name="www.abc.com" appBase="D:\Program Files\tomcat60\webapps" debug="0" unpackWARs="true" autoDeploy="true">
<Context path="" reloadable="true" docBase="D:\Program Files\tomcat60\webapps\abc" debug="0" />
</Host>
www.abc.com这里使用代替的.我有自己注册的域名.
这样的应用.
就出现outmemey 问题.我有配置msx内存.已经是1024M这个没有问题
加了<host></host>在work里会相应建立文件夹.
tomcat的这种运行机制怎么样的呢?
在没有使用apache的情况,到底怎么样配置.
