Еще один кошмар Tomcat / PermGen; Tomcat не запускается

Question

В прошлом я получал PermGen из-за ошибок пространства и просто перезапустил tomcat, чтобы исправить это. но теперь Tomcat вообще не запускается. это кот 5.5

вот вывод, когда я пытаюсь запустить Tomcat

Я думаю, что мой JAVA_OPTS выглядит нормально, но он все еще не запускается. кто-нибудь видит проблему ... спасибо
