As I told you, this box has only 16GB, and no swap. Only about half of
memory is used, and not from automatic tests (I would ruthlessly kill
Check your *own* job, it must have used 7GB or 8GB itself, making it the
biggest job running on this shared machine.
Or, it was something intermittent that ate all memory, in which case a)
it should work fine for you now; and b) please keep an eye out what it
is that is misbehaving.
