java - 关闭Google云平台Executorservice错误

Question

我有一个 Spring boot 应用程序，我在其中上传多个文件，提交后，它将所有文件转换为 byte[] 并将这些文件附加到电子邮件中。它在本地运行良好。当我上传超过5MB的文件时，但上传到Google Cloud Platform后无法正常工作。

以下是我收到的错误。

感谢任何帮助。

Answer 1

该问题是由于内存错误造成的。它未显示在 gcloud 日志控制台中。但我在 GCP 日志中看到了这一点。

下面是错误。

Exceeded soft memory limit of 256 MB with 322 MB after servicing 3 requests total. Consider setting a larger instance class in app.yaml
