This is in a container on a raspberry pi. Maybe some stuff is having issues in docker? 🤔

Pants requires 2GB by default:

\"/root/.cache/pants/lmdb_store/cache/3\": Cannot allocate memory"

I have 4.1 available? 🤔 Maybe this option? https://www.pantsbuild.org/docs/reference-global#section-pantsd-max-memory-usage Says says 4 gibibytes.. so like ~4.29GB cool thanks 😃
