What Sakai Does when You run out of Memory

Sakai will not start up with the default JVM settings. You need the following:
[csev@s-sakai-1 ~]$ grep OPT .bash_profile
JAVA_OPTS=’-Xmx512m -Xms512m -XX:PermSize=16m -XX:MaxPermSize=128m -XX:NewSize=128m -XX:+UseConcMarkSweepGC -XX:+UseParNewGC’ ; export JAVA_OPTS
Here is the message you get when you forget this:
