In the SymPy GitHub repository <https://github.com/sympy/sympy>, currently the only CI jobs that are failing are the Sage CI ones. I was investigating the workflows, and found that there are many instances of this warning: make -j8 build/make/Makefile --stop make[1]: Entering directory '/sage' make -j8 build/make/Makefile --stop make[2]: Entering directory '/sage' make[2]: warning: -j8 forced in submake: resetting jobserver mode. make -j8 build/make/Makefile --stop make[3]: Entering directory '/sage' make[3]: warning: -j8 forced in submake: resetting jobserver mode. make -j8 build/make/Makefile --stop make[4]: warning: -j8 forced in submake: resetting jobserver mode.
This error is repeated more than 5000 times, and then bash finally kills the process. According to this StackOverflow answer <https://stackoverflow.com/a/48388637/12591388>, to silence this warning, the number of jobs have to stay at the default number. I investigated some of the uploaded artifacts, and found the lines ARG NUMPROC=8 ENV MAKE="make -j${NUMPROC}" in the Dockerfile uploaded in the logs. While I am not sure whether this is the source of the error or not, silencing this warning should make finding the root issue easier. I was unable to figure out how this Dockerfile is constructed, so I am sharing my findings here.
