For documentation purposes mainly. I'm not sure to what extent this is a problem, but on some system shared memory is only 50% of RAM, which means that the user can only use 50% compared to local adaptivty option or no adaptivity.
It appears as if there is not enough space for /dev/shm/osc_sm.abc.1cbb0001.0.4 (the shared-memory backing
file). It is likely that your MPI job will now either abort or experience
performance degradation.
