Sorry for being unclear.

Is comming from my error database. Looking at the code it would have to do with the relative direction between two players being 180 causing the 0 devisor to appear. This function is being called by the game itself and not something which i can control.

_unit = _handleDamageArray select 0;
_shooter = _handleDamageArray select 3;
_dir = if (_unit == _shooter) then {
	0
} else {
	[_unit,_shooter] call bis_fnc_relativedirto;  // Might be 180
};
if (isNil "_dir") then {_dir = 0};	
_dirToFront = (180 - _dir) / 180; // Zero devisor if _dir is 180

This error happens about once every 250 hours of playtime on a deathmatch server.

The error is from the next line:

_dirToEnd = (abs _dirToFront / _dirToFront) - _dirToFront;
