As the subject says, NPCs are aggroing on each other. Usually one capship makes a mistake, then the rest of the dents (and some fighters) will disengage from the Levi to attack the victim NPC dent. The victim dent will just spin off away from the levi.

This has been observed at most the levis this week. But I think it has been observed off and on this year.
