我在生产环境中使用 Django 应用程序与 Celery 和 Amazon SQS 一起工作。每天在我的 celery 日志中我都可以看到有 SSL 错误:

[ERROR/MainProcess] Empty body: SQSError: 599 gnutls_handshake() failed: An unexpected TLS packet was received.

尝试重新连接到代理时出现下一个错误:

有时队列会在收到此消息后崩溃，我必须重新启动我的 Celery worker。一般来说，我不确定在收到此错误后 Celery 任务是否正在运行并正确执行。

解决这个问题的最佳方法是什么？

最佳答案

看来我已经找到了我的问题的答案。问题出在 kombu -> pycurl -> curl -> gnutls 中。 GnuTLS 库总是会丢弃 SSL 连接。所以我找到的唯一可能的解决方案是强制 libcurl 与 openssl 而不是 GnuTLS 一起工作。

这是我的分步指南 "How to reinstall curl"

对不起，伙计们，我的赏金会退还给我! ;-)
