So it isn't "working fine". It's not responding because it hasn't (better said can't) complete processing of the request (sql is failing). > Is there any way for me to recognize whether the mysql server is offline > from the radius server? You can use buffered-sql virtual server to deal with this - when database goes down NAS will get the response and accounting data will keep on piling up in the detail file until database is back on line. - List info/subscribe/unsubscribe?
