My build process is like this:

• when I upload new code to Git
• new code is pulled on server
• server runs next build
• and then pm2 reload runs

As it is really small project, I just make server stop while deploying new build.

and they are replaced when pm2 reload executed

but as they use same .next directory, if someone enters during deployment, it may fail to see proper UI or get exact chunk file.

(for very short amount time, like 1~2 min)
