Good Afternoon, I have a Freeradius (1.1.5) running on a server (1G RAM, double processor) as a Proxy Radius, on a production enviroment to AAA VOIP calls. At peak hours, the Radius stop responding. I cannot see any message on the log, just stop working. I have to kill/load manually in order to work again. Then, it appeared a message: "Error: Error receiving packet: Interrupted system call" I disabled all the logs (detail, pre_proxy_log, post_proxy_log), authorize/authenticate (chap, pap, etc), tunning some parameters like max_requests, thread pool, cleanup_delay, etc. Not running exec, hostname_lookups = no, etc.. Nothing special. The only thing I configured is: preproxy_users (in order to change de NAS-IP-Address), suffix (to identify the realm). At peak hours, one of the radius (behind the proxy) takes up to 14 seconds to answer. When it happens, there's a message in the logs like "Dropping conflicting packet from....". But not always, I mean, sometimes Radius stops working but there's no delay. So, what's going on?...Can somebody help me? Just in case, these are the values for most of the parameters: max_request_time = 20 delete_blocked_requests = no cleanup_delay = 2 max_requests = 2560 thread pool { start_servers = 10 max_servers = 50 min_spare_servers = 10 max_spare_servers = 10 max_requests_per_server = 250 } instantiate { } authorize { preprocess suffix } authenticate { } preacct { preprocess acct_unique suffix } accounting { } session { } post-auth { } pre-proxy { files } post-proxy { } Thanks in advance, Keiko. _________________________________________________________________ Explore the seven wonders of the world http://search.msn.com/results.aspx?q=7+wonders+world&mkt=en-US&form=QBRE
