Dear Jeff,
I did find a way to circumvent this issue for my specific application by
spawning less frequently. However, I wanted to at least bring attention to this
issue for the OpenMPI community, as it can
that there is a fundamental flaw in how OpenMPI handles dynamic
> process creation.

Subject: [OMPI users] MPI_Comm_spawn leads to pipe leak and other errors
Dear all,
My MPI application spawns a large number of MPI processes using MPI_Comm_spawn
over its total lifetime. Unfortunate
Dear all,
My MPI application spawns a large number of MPI processes using MPI_Comm_spawn
over its total lifetime. Unfortunately, I have experienced that this results in
problems for all currently supported OpenMPI versions (2.1, 3.0, 3.1 and 4.0).
I have written a short, self-contained program
