Google App Engine实例突然在标准环境中关闭

Question

We are using Google App Engine to ingest large amount of data to Google Cloud FireStore with below configuration:

Basic scaling instance_class: B4

basic_scaling: instances: 1

The overall data ingestion 0f 20GB takes around 1.5 hours. But we have noticed that some time after an hour, instance is abruptly shutting down with below error:

Container terminated on signal 9.

As per this documentation, basic scaling can serve he request up to 24 hours.

We can not see any more details in the logs as well. Also checked the memory usage, B4 has 1024 MB and the app is only utilising up to 700 MB.

If anyone has faced this kind of error, your input would be valuable!

Answer 1

Although the instance has 1024MB, the Operating System also needs some of that space - I guess that's why it shuts down. It's out of memory.
