[Building Sakai] "OutOfMemory: Permgen......" error deploying sakai 2.9.1

[Aaron Zeckoski]

It should run fine with that amount of ram. My tomcat setenv is this:
export JAVA_OPTS="-server -Xmx1028m -XX:MaxPermSize=320m
-Dcom.sun.management.jmxremote -Djava.awt.headless=true
-Dhttp.agent=Sakai
-Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false"

I suggest you drop the NewSize and I also suggest you do NOT set
JAVA_OPTS for your entire server environment but rather set it in the
tomcat setenv.

You might also consider using jstat or jvisualvm or some other
profiler to monitor the memory and see what is happening.

NOTE: my settings are for a development environment so you will want
to tune the Xmx and possibly other params a bit higher.
