I think the count of auth srv processes is fixed, no matter how many queries
coming( Can the count of auth srv processes be setted in runtime), but xfrin
processes is different. 
If one transfer-in with one process, My concern is there will be too many
xfrin processes at worst. Is there any other excuse?
