Question

I’ve an basic app that working fine when i’m runngin it with grails run-app, and I want to run it using grails run-war. But i’m always getting famous tomcat’s java.lang.OutOfMemoryError: PermGem space error, on any request, just after start.

Well, I know that I need to change PermSize value, so I tried all ways that i’ve found after googling (JAVA_OPTS, GRAILS_OPTS and grails.tomcat.jvmArgs), and now I have following script:

export JAVA_OPTS="-Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m"
export GRAILS_OPTS="-Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m"
grails -Dgrails.tomcat.jvmArgs="-Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m" run-war

but it doesn’t help. Still having java.lang.OutOfMemoryError: PermGen space on first request.

What i’m doing wrong? Is there any other way to configure PermSize for Grails 2.0.1?

Update: I run ps -ef | grep java and found that Grails actually got my params, but then it ran a new process, for tomcat, w/o this params.

Answer 1

Found that it must be configured at BuildConfig.groovy:

grails.tomcat.jvmArgs= ["-Xms256m",  "-Xmx1024m", "-XX:PermSize=512m", "-XX:MaxPermSize=512m"]

Now it’s working fine.
