[Freeswitch-users] rad_auth failing under load

[Joseph Waite]

Hi Guys

I am having a strange issue, when I have more than about 450 concurrent calls, rad_auth seems to fail to authorise calls.

I see the Radius request received and replied with RAD-ACCEPT from the Radius server but I get the following error

2017-08-07 18:29:53.202133 [ERR] mod_rad_auth.c:504  RADIUS Authentication failure (RC=1)
2017-08-07 18:29:53.202133 [ERR] mod_rad_auth.c:702 An error occured during radius authorization.

I have had a look as ulimit and seems to be fine.

Anyone have any ideas?
