I am running NWchem (a quantum chemistry program) in parallel on a single host using mpich-3.2.1_6 on FreeBSD 12.1 It runs, but every once in a while hydra_mpi_proxy sends SIGKILL to a client process nwchem. The same task usually succeeds when rerun again, and some other task fails with SIGKILL next time, so the problem is sporadic. Why does hydra_mpi_proxy kill client processes? My original NWchem bug report is https://github.com/nwchemgit/nwchem/issues/198 Thank you, Yuri
