Я столкнулся с проблемой, что Tomcat8 создает несколько работающих экземпляров, так что во время старта я получаю исключение, что адрес уже используется:Tomcat 8 начинает несколько раз [LifecycleException]

Я думаю, что проблема может быть в разъеме server.xml, который я принял от предыдущего Tomcat 6.
Однако, я действительно понятия не имею, почему новый экземпляр создается каждый раз, когда Tomcat перезагружается и будет получать любую помощь.
