i dont know, i was looking for a war zone (high or low intensity) but there were none.
that was a discovered system (more or less - i'm nor sure, i dont remember if i ever explored malloc in detail and actually i just have a plain a basic discovery scanner on this ship)
but the problem solved itself: i stumbled upon a dude offering me an abandon option - an option i was unable to refuse because, well, there were no other option... just like with the "abandon killing pirates"-thing.
no alternatives, just a fact: "you just abandon this mission". period.
(not so) nice... :-/
