Package: src:openfoam Version: 1812+dfsg1-1 Severity: important looking in the build logs you see a lot of
make[5]: warning: -j3 forced in submake: resetting jobserver mode. warnings. So the build doesn't respect the -j3 passed from the toplevel and uses more resources than it should for the build. Please fix the build to respect the amount of parallelism as asked by the builders.
