no stack trace yet however impala at least seems to be running out of
memory (!) with 380MB of RAM and some 800MB of swap(and no other tasks)
during the regression run. Maybe something is causing a dramatic
increase in memory usage that is causing the random failures (in impalas
case the OOM-killer actually decides to terminate the postmaster) ?
