[Serusers] Questions about ser

Hello, I'm using several modules that access a database. I've noticed that when I start ser in forked mode with "children=8", it generates 62 connections to database. Does every child open a separate set of database handles (one for every module)? I remember I saw on the mailing list advises to run ser with hundreds of children to avoid problems when no workers are available to process a message. If my guess is true it would generate hundreds (or even thousands) of database connections. I'm really interested to hear how people out there deal with it. On a separate note I'm curious whether number of children in ser is limited to a given startup value or ser is able to fork additional children as needed? Thank you, Michael
