[OpenSIPS-Users] Opensips 2.1 custom radius accounting error

[Ionut Ionita]

Hi Arsen,

     If i completely understand the problem, the server doesn't provide 
the deserved response. The problem in this case is that rc_send_server 
function which is used by rc_acct function (which gives you the error) 
uses a blocking socket and recvfrom blocks until it receives the RADIUS 
message response. You can see the source code here [0] line 224. 
Blocking causes  problems in scheduling other timers in opensips, in 
your case tm and dialog timers, and that is the cause for your warnings. 
So it is a drawback of the freeradius-client(or radiusclient-ng) 
implementation. We tried to solve this problem in opensips 2.2 with 
radius async features[1].

Regards,
Ionut-Razvan Ionita
