Hi, We are having an issue where, in some sessions, an Authentication Request is sent successfully (and inserted into RADPOSTAUTH table), but the Accounting Start Query is never run/received. Subsequently, Accounting Update Queries come through, but fail due to the fact that a relevant RADACCT session has not been inserted to begin with. It only happens in a small amount of cases, < 1% of sessions, but nonetheless opens us to loss of data that is not being billed for properly. Is this a known issue? Is there a workaround? We're looking at changing the Acct Update Query to insert a new session if it cannot find an existing one. Any help will be appreciated. henk -- Henk Kleynhans CTO & Founder Skyrove (Pty) Ltd Technology Top 100 - Most Promising Emerging Enterprise 2006 Tel: +27 (21) 4488843 Cell: +27 (84) 3073451 Fax: +27 (86) 6204077 henk@skyrove.com blog: www.geekrebel.com ------ "A person with ubuntu is open and available to others, affirming of others, does not feel threatened that others are able and good, for he or she has a proper self-assurance that comes from knowing that he or she belongs in a greater whole and is diminished when others are humiliated or diminished, when others are tortured or oppressed." - Desmond Tutu
