Hi, See thread below. I've just uploaded 3.1.2-5 which I believe fixes the hangs due to OpenMPI ( non-atomic handling of sending a 64-bit tag, occuring mostly on archs with 32-bit atomics).
Awkward observation: openmpi 3.1.2-5 now causes dolfin tests to timeout (on amd64)
https://ci.debian.net/packages/d/dolfin/unstable/amd64/ Tracker page pings lammps and liggghts as well. Drew
