OK. We are testing with sql_log. The system load ist significant lower now. Uptime went from 0.3 to 0.05. But still we see the same amout of "error duplicate packets" in the radius log. I would not be worried at all about that, the the CPU load of the NAS (radius client) is 100%. Perhaps the client drops the accout reply packets? -- Dr. Michael Schwartzkopff MultiNET Services GmbH Addresse: Bretonischer Ring 7; 85630 Grasbrunn; Germany Tel: +49 - 89 - 45 69 11 0 Fax: +49 - 89 - 45 69 11 21 mob: +49 - 174 - 343 28 75 mail: [EMAIL PROTECTED] web: www.multinet.de Sitz der Gesellschaft: 85630 Grasbrunn Registergericht: Amtsgericht München HRB 114375 Geschäftsführer: Günter Jurgeneit, Hubert Martens --- PGP Fingerprint: F919 3919 FF12 ED5A 2801 DEA6 AA77 57A4 EDD8 979B Skype: misch42 - List info/subscribe/unsubscribe?
