Stuck Thread Weblogic

Question

최대 절전 모드에서 spring mvc를 사용 중이며 응용 프로그램이 weblogic에서 호스팅됩니다. DAO IMPL을 통해 몇 개의 최대 절전 모드 호출에서 스레드 문제가 발생합니다. 누구든지 앞으로 나아갈 방법을 제안 할 수 있었습니까?

Answer 1

문제가 발생한 곳은 Session.close();이며 많은 곳에서 구현되지 않았습니다.

Answer 2

정말로 걸림돌입니까, 아니면 오래 실행되는 서비스입니까? Weblogic은 기본적으로 StuckThreadMaxTime보다 더 오래 실행되는 스레드를 표시합니다.이 스레드는 기본적으로 600입니다. 실제 문제인지 아닌지 확인해야합니다. 그렇지 않은 경우 StuckThreadMaxTime을 더 높은 값으로 늘리면이 오류가 발생하지 않습니다. 응용 프로그램 문제점 인 경우, 응용 프로그램에서 발견되어야합니다.
