Java 关闭Google云平台中的Executorservice错误

我有一个Spring boot应用程序，我上传了多个文件，提交后，它会将所有文件转换为

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，但上传到谷歌云平台后，它就不能正常工作了

下面是我得到的错误

非常感谢您的帮助。

问题是由于内存错误造成的。它没有显示在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

从您的描述来看，SpringWeb的Maven/Gradle依赖项设置正确，GCE防火墙规则正常（因为该应用程序暗示为内容提供服务）。GCE实例不会对应用程序本身做任何更改（它们只是VPS），所以我猜问题出在您的Java环境中。为了排除GCE，你能提供更多的细节吗？此输出仅指向与Java环境本身相关的执行器错误，而不是GCP。感谢@yyyyahir的评论。我做了很多研究后才发现。很长一段时间以来，我只看到了gcloudsdk的日志。但是从GCP帐户的日志中，我知道这是因为我的软内存超过了限制。很高兴知道。也许值得发布一个答案供将来参考？由你决定。谢谢，当然可以。我会把它作为答案贴出来。非常感谢。
