The server has 64GB or RAM Jay, and each DC instance is configured with db_shared_buffers: "4096MB".
Also these further issues haven’t been on rebuild, but seem to be the remnants of that original issue.
I will clean up docker ./launcher cleanup to see if that helps, but if you or anyone else has any other ideas in the meantime that will be greatly appreciated.
Edit: just noticed something weird after running docker container ls -a, will post a new thread about it.
