I am using a GCE E2 instance, and since around May 2023, the following kernel errors have been output to "/var/log/messages".

Is this a problem?

 

# cat /etc/redhat-release
Rocky Linux release 8.7 (Green Obsidian)

Hello @Takeshim,

Welcome to Google Cloud Community!

Your question has something to do with your OS and not with GCP. You might want to check this post regarding page allocation failure. 

Thanks!
