장고 mod_wsgi에 MemoryError의

Question

내 장고 프로젝트에 MemoryError의와 이상한 문제를 가졌어요.

• 우분투 11
• 아파치
• Nginx에
• mod_wsgi에
• python2.7

내가 PIL을 사용하여 이미지 크기를 조정하고 내 dev-에서 잘 작동되는 템플릿 태그가 머신에서 작동하지만 생산시에는 큰 이미지 (~ 800px)에서 500 오류가 발생합니다. 템플릿 태그는 원본 이미지가 이미 매우 작을 때만 문제없이 작동하는 것처럼 보입니다. 같은 오류가 - 템플릿 태그는 그냥 python2.7에 대한 mod_wsgi에 재 컴파일 시도

http://djangosnippets.org/snippets/1944/의 수정 된 버전입니다.

더 많은 메모리 아니면 뭔가 다른 내가 그냥 이해하고 있지 않다 할당 할 수있는 방법이 있나요?

도움이 될 것입니다. 역 추적이 나에게 이메일로 전송

은 다음과 같습니다

감사합니다.

은 분명히 CTYPE 모듈에 대한 __init__.py에 이상한 버그가있다. - 또는 무엇이든, 방금 읽었습니다.

최소한 수정 사항은 __init__.py 파일의 마지막 줄을 주석 처리하는 것이 었습니다. 마지막 줄이 Windows 64 비트 전용이고 우분투를 망가 뜨리는 것 같습니다.
