MySQL connection setup

Hi Friends, There is a configuration in SQL.conf. Num_sql_socks= I would like to know if this value is set to smaller, fx. 20, can it cause breaking stream or disconnecting for DSL users? If I set it to larger, can it cause MySQL problem of “Too many connection”. I can’t find details information about this setting in SQL.conf file. I want to know what policy of setting numbers is. Thank you very much. Robin
