Hmm, ok my eat mem was useless. Could not get the system to crash ...
Thank I was thinking and it occured to me that each time I was experiencing the crashes thgere was heavy file system activity.
So I tried two things:
tar cf /dev/null <large directory 500+MB>
That went ok, than I did:
tar cf archive.tar <large directory 500+MB>
And that gave me:
