[OMPI users] segfault (shared memory initialization) after program ended

[Oliver]

hi -

I have an application that consistently segfault when I do
"mpirun --oversubscribe" and the following message came AFTER application
runs. My running environment: MacOS with openmpi 3.1.2.

Is this a problme with my application? or my environment? any help?

thanks

Oliver

A system call failed during shared memory initialization that should
not have. It is likely that your MPI job will now either abort or
experience performance degradation.
