[NEST Users] Re: MPI-based error on v3.8

Robin: "Ok, is this error raised during install check / nest test, or is this raised during one of your own simulations?" No errors are raised during install check. nest test creates one failure for regression test. The crash always occurs during my simulations. Robin: "I think one of the possible causes of that error is that you have too many neurons on a single node. Could you start by trying a small proof of concept simulation, perhaps one of the nest examples, or something similarly simple." Done. I tried reducing the number of neurons from ~5000 to ~1000 in the test network. The simulation lasted two more iterations, but ultimately crashed with the same error. I also tried this with a NEST example (https://nest-simulator.readthedocs.io/en/stable/auto_examples/structural_pl…) modified for MPI, and it too crashes with the same error. I'm still working on more tests, and will post here once I have more information.
