최근 2.8.0.beta2로 이어진 업그레이드 열풍 속에서, 현재 조사 중인 이상한 현상이 발생했습니다. 다중 사이트 설치 환경에서 일부(모두는 아님) 서브 사이트가 더 이상 응답하지 않는다는 것입니다. 메인 사이트는 정상적으로 작동하며, 일부 서브 사이트도 정상적으로 운영되고 있습니다.
~~이 문제가 안정판에서 이미 보고된 [discourse-calendar](https://meta.discourse.org/t/discourse-calendar/97376/234?u=hellekin) 이슈와 관련이 있을 것으로 추정되지만, 이는 단순한 추측일 뿐입니다.~~

먼저 `git pull`을 실행하셨나요? (부트스트랩 대신 리빌드를 수행하는 경우 불필요합니다.)
또 하나의 추측이지만, 테마와 관련이 있을 수도 있습니다.
테마와 플러그인을 확인해 보세요. 안전 모드를 시도해 보셨나요?

@pfaffman님 감사합니다. `rebuild`를 두 번 실행했고 `safe-mode`도 적용해 보았지만 도움이 되지 않았습니다. 현재 멀티사이트 문제를 피하기 위해 다른 머신에서 다시 빌드 중이며, 백업에서 복원하면 해결될지 확인해 보고 있습니다.
추가로 말씀드리자면: 게시된 페이지(`/pub` 아래)는 정상적으로 작동합니다. 아, `/admin`도요… 어쩌면 제가 해결할 수 있을지도 모르겠네요…
* * *
아마도 이 사이트에서 비활성화된 `discourse-prometheus-alert-receiver` 플러그인에서 비롯된 것 같습니다…

아래 줄이 문제의 원인으로 보입니다. 하지만 플러그인이 비활성화되어 있으므로 실행되지 않아야 하지 않나요?

`discourse-prometheus-alert-receiver`가 활성화되어 있으면 사이트가 정상적으로 작동합니다. 그러나 **활성화되지 않으면** 사이트가 오류를 일으킵니다. 이것은 버그로 보입니다.
