Curious, has anyone seen a buildpack with a manifest file work in one segment, but that same app and manifest file not work in an isolation segment?  What happens is you run cf push app name, the app fails at the droplet stage, although you can still manually start the app. Do note that the underlying resources are identical, diego cells, and the buildpack is NGINX.  Adding more memory to the manifest does solve the issue, 1GB to 2 GB, but curious why more memory would be needed between two different segments.  Nothing here stands out https://docs.cloudfoundry.org/adminguide/isolation-segment-index.html. other than networking.  I am in discussions with Pivotal but wanted to see if anyone here had issues like this elsewhere?  It's just a weird problem to say the least.
