Hello Everybody,

I'm new using Freeswitch and now I'm implementing it as a B2BUA using Radius (using the module mod_xml_radius) for Accounting and Authentication. Everything work OK until freeswitch has more than 260 simultaneous calls, after that  the cli shows errors:

2016-08-18 16:23:24.314356 [ERR] mod_xml_radius.c:1046 mod_xml_radius:  Accounting Stop failed
2016-08-18 16:23:24.454362 [ERR] mod_xml_radius.c:1109 mod_xml_radius: Failed to authenticate, authentication result: 1

Meanwhile, the messages file shows the following errors:

rc_ip_hostname: couldn't look up host by addr: "HEXAIPADRRESS"
rc_send_server: no reply from RADIUS server unknown:1646, "IPADDRESS"

It looks like it's timeout, however my Radius server is responding OK to another server's requests.

I'm using Freeswitch 1.6.9 compiled from source.

Best Regards,
Juan Pablo Godoy.
