(migrated from internal issue tracker)

Running an NRW 300x300 case on a JURECA node with 64 MPI tasks+2 OpenMP threads throws a segfault (13391550.eclm.out.txt, 13391550.eclm.err.txt). Same result with hyperthreading (32 MPI tasks+4 threads). Next thing to figure out is if this issue can be easily resolved by some right combination of namelist+jobscript settings.
