Can't say. You observed timeouts, which could be consistent with drivers or
runtimes getting stuck. However, the other mdrun processes may have by
default set thread affinity, and any process that does that will interfere
with how effectively any others run, such as the tests. Sharing a node is
difficult to do well, and doing anything else with a node running GROMACS
is asking for trouble unless you have manually managed keeping the tasks
apart. Just don't.
