Help pls with one script

[OmarAcero]

I had this error:   HERE    ( run_script: infinity loop ! )

----

Friends, I think I almost got it after studying all the code, I discovered where it originates:   

I found it in the next NPC, i am increasing and playing,  "NEXT; ".     NOTE 

But now I get an error called:   script_rid2sd: fatal error !  player not  attached! 

My question is this normal?

function        script  BKLoadConfiguration     {
        debugmes "BotKiller 6: Loading configuration...";
        query_sql "select count(*) from `bk6_config`",.@Cnt$;
        set .@Page,0;
        set .@PageSize,50;
        set .@TotParams,.@Cnt$[0];
        while (.@TotParams > 0) {
                set .@Cfg, query_sql("select `var`, `value`, if(right(`var`,1)='$',1,0) `str` from `bk6_config` limit " + .@Page + "," + .@PageSize,.@Var$,.@Val$,.@Str);
                if (playerattached())
                        dispbottom "BotKiller 6: Processing " + .@Cfg + " parameter(s)...";
                else
                        debugmes "BotKiller 6: Processing " + .@Cfg + " parameter(s)...";
                for (set .@x,0; .@x < .@Cfg; set .@x, .@x + 1)
                        if (.@Str[.@x]) setd .@Var$[.@x],.@Val$[.@x]; else setd .@Var$[.@x],atoi(.@Val$[.@x]);
                set .@TotParams, .@TotParams - .@PageSize;
                set .@Page, .@Page + .@PageSize;
//              sleep2 2000;
//              next;
        }
 
        debugmes "BotKiller 6: " + .@Cnt$[0] + " parameter(s) loaded";
        sleep2 2000;
        debugmes "BotKiller 6: Loading map ignore list...";
        set .@Cnt,1;
        set .@Page,0;
        while (.@Cnt) {
                set .@Cnt, query_sql("select mapname from bk6_maps limit " + .@Page + ",100",.@IgnoredMap$);
                for (set .@x,0; .@x < .@Cnt; set .@x,.@x + 1) {
                        setd "$@_" + .@IgnoredMap$[.@x],1;
                }
                set .@Page, .@Page + 100;
                next;  // writing this NEXT; (For example cured the infinity loop)
        }
//        sleep2 1000;
        if (playerattached()) dispbottom "Reload Configuration: Complete!";
        return;
}

use...

freeloop(1);

or with eAthena...

if ( ! ( set(.@l,.@l+1) % 600) )
	sleep2 1;
