Are you still on Solaris boxes? I am using these settings on 
some RHEL5 boxes running Sakai 2.6:

# SAK-10159
SAKAI_HTTP_AGENT="-Dhttp.agent=Sakai"

# SAK-17425
SAKAI_TOMCAT_OPTS="-Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false"

# JDK 1.6
SAKAI_JDK16="-Dsun.lang.ClassLoader.allowArraySyntax=true"

JAVA_OPTS="-d64 -Xmx6144m -Xms6144m -Xmn1g -XX:MaxPermSize=512m -XX:PermSize=512m -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSClassUnloadingEnabled -XX:+DisableExplicitGC -Dsun.rmi.dgc.server.gcInterval=600000 -Dsun.rmi.dgc.client.gcInterval=600000 -Dfile.encoding=utf-8 -Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -verbose:gc -Xloggc:/var/log/tcat/sakai/sakai_gc.log -XX:+PrintGCDetails -XX:+PrintGCTimeStamps ${SAKAI_SECURITY} ${SAKAI_HTTP_AGENT} ${SAKAI_TOMCAT_OPTS} ${SAKAI_JDK16}"
