The following statement is in run.conf
# # Specify options to pass to the Java VM. # if [ "x$JAVA_OPTS" = "x" ]; then JAVA_OPTS="-Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000" fi
I assume it's trying to detect if people are passing in via the command line memory settings and therefore not use the ones configured...
