It turned out that i'm unable to reproduce it, too. In all other tests
tcp, sysv, usysv ran through tests smoothly. What concerns other rpi's,
i haven't tested them very much. However, when i try to run one problem
in "hypre" on, say, 30 or more processors using "sysv" or "usysv" it
almost always crashes with a message like this:
--------------------------------------------------------------------

On the other hand, it runs fine with "tcp".
