For your custom mobs, the map server is stating that you don't have enough columns inside your custom mobs lines.. you need a total of 57 and you don't have that many. What you need to do is count the columns rAthena has in the mob_db and make sure you add any missing columns to your custom mob scripts.
ID,Sprite_Name,kROName,iROName,LV,HP,SP,EXP,JEXP,Range1,ATK1,ATK2,DEF,MDEF,STR,AGI,VIT,INT,DEX,LUK,Range2,Range3,Scale,Race,Element,Mode,Speed,aDelay,aMotion,dMotion,MEXP,MVP1id,MVP1per,MVP2id,MVP2per,MVP3id,MVP3per,Drop1id,Drop1per,Drop2id,Drop2per,Drop3id,Drop3per,Drop4id,Drop4per,Drop5id,Drop5per,Drop6id,Drop6per,Drop7id,Drop7per,Drop8id,Drop8per,Drop9id,Drop9per,DropCardid,DropCardper
Is your server in Renewal mode?
/// renewal drop rate algorithms
/// (disable by commenting the line)
///
/// leave this line to enable renewal item drop rate algorithms
/// while enabled a special modified based on the difference between the player and monster level is applied
/// based on the http://irowiki.org/wiki/Drop_System#Level_Factor table
#define RENEWAL_DROP
The drop system for Renewal servers are a lot different than Pre-renewal.
