Tomcat 5.5.x and 6.0.x

Grails 1.6.x

Java 1.6.x

OS CentOS 5.x (64bit)

VPS Server with memory as 384M

export JAVA_OPTS='-Xms128M -Xmx512M -XX:MaxPermSize=1024m'

I have created a blank Grails application i.e simply by giving the command grails create-app and then WARed it

I am running Tomcat on a VPS Server

When I simply start the Tomcat server, with no apps deployed, the free memory is about 236M and used memory is about 156M

When I deploy my "blank" application, the memory consumption spikes to 360M and finally the Tomcat instance is killed as soon as it takes up all free memory

As you have seen, my app is as light as it can be.

Not sure why the memory consumption is as high it is.

I am actually troubleshooting a real application, but have narrowed down to this scenario which is easier to share and explain.
