FreeRadios rlm_sql dumps if databaase server hiccups

Hi, We use FreeRadius with unixODBC and the rlm_sql to connect to a Microsoft SQL database. All works great... except if the SQL database goes down, firewall has the translate table, someone trips over a network cable.... anything that causes the connection between the radius and SQL to be disturbed, it just says "There are no DB handles available...." instead of reconnecting... the only way I've found to reconnect, is to restart... Any comments or thoughts on this problem?
