Сервер Tomcat выключается через несколько секунд после запуска?

У меня какая-то странная проблема на моем сервере tomcat на ПК ubuntu, он может запуститься после запуска через несколько секунд, и он будет отключен. Тем не менее я не мог запустить сервер Tomcat

у моего server.xml нет ошибки, я меняю порты, тоже не повезло

это мой конфиг

<Connector port="8080" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" />

любая помощь?

мой журнал ошибок catalina.out говорит
