나는이 예외 상황에 자주 직면하고 있습니다.잠금을 시도 할 때 교착 상태가 발견되었습니다.
2015 1 월 06 14 : 24 : 59.167 잠금 출처 = Data.ResultAccumulator
를 얻을 수하려고 할 때 발견 [0] System.Exception 메시지 = 교착 상태 잠금을 얻으려고 할 때 발견 (심한 경우도 있음) 교착 상태
내 응용 프로그램은 VB.Net 응용 프로그램입니다 및 DataAdapter.Update 방법 나는이 예외를 얻고에서의 DataTable을 사용하여 일괄 갱신을하는 동안 나는 닷넷 버전 6.8.3
에 대한 MySQL의 연결을 사용하고 있습니다. 전체 업데이트 프로세스가 트랜잭션에서 실행 중입니다.
사용자가 Innodb 상태를 분석하도록 제안한이 예외가있는 다양한 스레드가 발견되었습니다. 그래서 나는이 예외를 얻은 후에 그 상태를 취했습니다. 그러나 나는 그것을 분석하는 방법을 모른다. innodb 상태가 있습니다.

을 내 이 교착 상태 예외를 포착 한 로그 파일 만 'show engine innodb status'명령을 실행하여 상태를 찾습니다. 진행중인 트랜잭션이 롤백 된 예외로 인해 예외가 발생한 동일한 트랜잭션 내에서이 트랜잭션을 실행해야합니까? 그런 다음이 상태를 취했습니다. – user4259788
