Being disabled, it can can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

Danke Michael, es scheint, dass es ein Verstoß gegen die Namenskonvention von Zeitwerk war! (wird von Rubocop nicht erkannt, funktioniert aber in der Entwicklung).
Aber diese Befehle sind sehr, sehr nützlich für zukünftige Referenzen!
