Source: adios2 Followup-For: Bug #1062356 The flakey test is adios2-mpi-examples. debian/tests is building and running them manually, and running on only 3 processors (mpirun -n 3) So the problem can't be overload of the machine.
I'll just skip insituGlobalArraysReaderNxN_mpi. For reference, upstream is making some changes to make it more reliable to run tests against the installed library, https://github.com/ornladios/ADIOS2/pull/3906 also https://github.com/ornladios/ADIOS2/pull/3820 Not certain that that directly makes insituGlobalArraysReaderNxN_mpi more reliable though.
