Unable to have log4j write to RollingFileAppender in Grails - grails

Question

I have a grails 2.3.11 plugin and application with the following log4j configuration in the Config.groovy and when I run it on the server, info and error messages do not get logged into my rollingFileAppender. When I run the application locally the messages get logged susccessfully to the console though.
myapp.log does get created under my tomcat/logs folder. However, messsages do not get written into it.
Any suggestions?
log4j = {
