Help understanding specific error spamming RPT

[DangerRuss]

Constantly getting people spawning in as birds when the server resets. This goes on for awhile and eventually fixes itself. Getting this spammed in my RPT a lot

if (!(_i in dayz_location>
2:21:02   Error Zero divisor
2:21:02 File z\addons\dayz_server\compile\fa_hiveMaintenance.sqf, line 365
2:21:02 Error in expression <distance [_location select 0, _location select 1, 0];

So I checked that line in my fa_hiveMaintenance.sqf and it reads

364  // cancel the change if it is too near original pos
365   if (([(_this select 1),_a] call BIS_fnc_distance2Dsqr) <= 30) then {
366     [_this select 0, +(_this select 1)]
367  }
368   else {
369       [ _dir, [_a select 0, _a select 1, 0]]
370  }
371 };

Im not sure how to fix this or where this error stems from. Please help and thanks
