同样遇到这个问题，目前我的解决方案是增加client_body_buffer_size,并关闭client_body_in_file_only,感觉问题在于POST数据过大的时候，不能写入缓存。

@maqingshan 相关原因可参考这个 https://github.com/alibaba/tengine/issues/1109
当前正在升级core代码，届时会支持http2的流式上传功能，从根上解决这个问题。

感谢答复，期待升级

最新的 tengine 中已经修复了这个错误。

Tengine-2.3.0已发布，已升级至nginx 1.15.9。

新版本更多详细信息请参见https://github.com/alibaba/tengine/issues/1220。
