httpd가 /usr/lib64/httpd/modules/mod_ssl.so의 ssl_io_filter_cleanup()과 충돌합니다.

버전: httpd-2.4.54-1.el8.x86_64

작업에 대해 httpd condrestart를 수행하면 코어가 생성되고 코어 파일 pid와 관련된 일부 ssl_error_logs도 볼 수 있습니다.

나는 이것에 익숙하지 않기 때문에

  • 코어를 생성하는 이유 또는 mod_ssl.so의 문제점은 무엇입니까?
  • httpd 관점에서 코어 생성 문제를 해결하는 방법은 무엇입니까(가능한 경우)?
