Good Afternoon,<BR>
<BR>
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.<BR>
<BR>
At peak hours, the Radius stop responding. I cannot see any message on the log, just stop working.<BR>
I have to kill/load manually in order to work again. Then, it appeared a message:<BR>
"Error: Error receiving packet: Interrupted system call"<BR>
<BR>
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.<BR>
<BR>
Not running exec, hostname_lookups = no, etc.. Nothing special.<BR>
<BR>
The only thing I configured is: preproxy_users (in order to change de NAS-IP-Address), suffix (to identify the realm).<BR>
<BR>
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.<BR>
<BR>
So, what's going on?...Can somebody help me?<BR>
<BR>
Just in case, these are the values for most of the parameters:<BR>
max_request_time = 20 <BR>
delete_blocked_requests = no<BR>
cleanup_delay = 2 <BR>
max_requests = 2560 <BR>
thread pool {<BR> start_servers = 10<BR>
max_servers = 50 <BR>
min_spare_servers = 10<BR> max_spare_servers = 10 <BR>
max_requests_per_server = 250<BR> }<BR>
instantiate {<BR>
}<BR>
authorize {<BR> preprocess<BR> suffix<BR> }<BR>
authenticate {<BR>
}<BR>
preacct {<BR> preprocess<BR> acct_unique<BR> suffix<BR> }<BR>
accounting {<BR>
}<BR>
session {<BR>
}<BR>
post-auth {<BR>
}<BR>
pre-proxy {<BR> files<BR>
}<BR>
post-proxy {<BR> }<BR><BR>
Thanks in advance,<BR>
