문제점을 이해하지 못합니다. 어느 누구도이 문제를 해결할 수 있습니까?웹 응용 프로그램을 배포 할 때 메모리 누수가 발생했습니다.

Java 프로세스를 강제 종료 할 때마다 Tomcat이 다시 시작됩니다.

10 분에서 15 분 동안 정상적으로 작동하고 매번 중단됩니다.

웹 응용 프로그램에 여러 가지 문제가 있습니다.

응용 프로그램과 함께 servlet-api.jar의 모든 버전을 패키지하지 마십시오. 컨테이너가 제공합니다.
웹 응용 프로그램이 중지되면 드라이버의 등록을 취소해야합니다.
ThreadLocals의 사용에 신중을 기해야합니다. ThreadLocal은 단일 요청의 범위 밖에 존재해서는 안됩니다. http://people.apache.org/~markt/presentations/2010-11-04-Memory-Leaks-60mins.pdf
