Hello! I'm using a FreeRadius setup (V 1.1.3-3 from Debian etch) with the MySQL Backend for authorize and accounting. RADIUS packets are coming from another company, which /probably/ has a Proxy for their delivery front-end servers. This setup usually works fine, but on some days I see spikes in the log, and the radiusd process vanishes; needing a restart. I've set: max_request_time = 5 cleanup_delay = 5 max_requests = 4096 sql.conf: num_sql_socks = 256 nas: nastype = other Usually, there will be a few 'stop packet with zero session length' log lines, about 1 per second or fewer. At problem/spike time, I see a lot more of these 'stop packet with zero session length' stuff (about 30 per second); and this too: Info: The maximum number of threads (256) are active, cannot spawn new thread to handle request Additionally, one of these things happen: 1) radiusd process vanishes without a log entry. 2) Error: Dropping request (4097 is too many): from client nasname:57426 - ID: 174 Info: WARNING: Please check the radiusd.conf file. ?The value for 'max_requests' is probably set too low. 3) Error: Internal error processing module entry And radiusd usually vanishes after this. With Option 3 I usually also see MySQL DB connection problems, but not all the time, and they are not always fatal (?). So - am I missing something? Is this just a very long spike (can take 10 minutes to a few hours); Are there any counters in FR that I could track? (like packets per second, etc.) Thanks, Christian -- Christian Hofstädtler InQnet GmbH Praterstraße 31 A-1020 Wien Tel.: +43 1 212 7650 523 Fax.: +43 1 212 7650 610
