Error in log

[BetterDeadThanZed]

I'm getting this error over and over in my log:

DZMSPurgeObject = {
_>
 2:52:55   Error position: <_sleepTime;};
};


DZMSPurgeObject = {
_>
 2:52:55   Error Undefined variable in expression: _sleeptime
 2:52:55 File z\addons\dayz_server\DZMS\DZMSFunctions.sqf, line 258
 2:52:55 Error in expression <nterval; (diag_tickTime - _startTime) > _sleepTime;};
};

Any ideas? Line 258 of DZMSFunctions.sqf is this:

waitUntil{sleep _checkInterval; (diag_tickTime - _startTime) > _sleepTime;};

DZMSSleep = {
    private["_sleepTime","_checkInterval","_startTime"];
	
    _sleepTime = _this select 0;
    _checkInterval = _this select 1;
	
    _startTime = diag_tickTime;
    waitUntil{sleep _checkInterval; (diag_tickTime - _startTime) > _sleepTime;};
};

Thats my DZMSSleep,  I don't get that error :P

Same as mine.

try putting  

if (isNil "_sleepTime") then {
    _sleepTime = 0;
};

above _sleepTime = _this select 0;
