Storage of Null values in Teradata

In Teradata data distribution is done by hashing the Primary index value.It means that hashing the null values for all tables will go to a single AMP.So the single amp gets over burdened which result in HOT AMP condition.If the AMP has storage capacity of only 20 null records and if it receives a 21st null record then where would the 21st null record insert???
