This should probably be investigated. For the larger model (`N_160_M_160`), it is still in the front-end connection handling after running for 3 hours. But if it would pass through to the backend, it would get stuck there as well."	defect	closed	high	1.11.0	Backend	v1.9.4-dev-nightly	fixed		Francesco Casella Lennart Ochel Patrick Täuber Bernhard Bachmann
