파이썬 3 스레드가 스레드 수보다 큰 작업을 실행하지 않습니다.

Question

실행하지 않는 스레드에 문제가 있습니다. 나는 스레드를 설정하는 방법에 관한 문서를 따라 갔고 첫 번째 일괄 처리를 마친 후에는 스레드가 작동하는 것을 제외하고는 훌륭하게 작동합니다. 기본적으로 원격 서버 로그 디렉토리를 로컬에 마운트 한 다음 두 개의 특정 문자열에 대한 로그를 구문 분석합니다. 처음 10 개의 스레드가 끝나면 서버가 멈추고 결코 넘어지지 않습니다. 내가 도대체 ​​뭘 잘못하고있는 겁니까?

Answer 1

.run() 방법은 큐에서 한 아이템을 처리 한 후 종료한다. 변경 대상 :

while True: 
    job = q.get() 
    # ... 

코드에 다른 많은 문제가 있습니다.
