IDEA8无法关闭tomcat问题

请教各位大哥大姐，我在intelliJ中能启动tomcat，但是无法关闭，日志如下：
cmd /c G:\tomcat-7.0.0\bin\catalina.bat stop
Using CATALINA_BASE: "C:\Users\asus\.IntelliJIdea8x\system\tomcat\Unnamed_AjaxLearning97d68952"
Using CATALINA_HOME: "G:\tomcat-7.0.0"
Using CATALINA_TMPDIR: "G:\tomcat-7.0.0\temp"
Using JRE_HOME: "C:\jdk1.6.0_21"
Using CLASSPATH: "G:\tomcat-7.0.0\bin\bootstrap.jar;G:\tomcat-7.0.0\bin\tomcat-juli.jar"
Error occurred during initialization of VM
Could not reserve enough space for object heap
Disconnected from server
每次都只好关闭IDEA后在进程中强制干掉tomcat进程，非常不方便，求解？
