Hello, I'm sorry to bother everyone with these mails, but I'm discovering things (I'm completely new in Freeswitch) and probably this will help someone in the future. The problem is not caused by DNS at all. The reverse resolv it's used by Radius client just for logging purposes. I gave a FQDN to each Radius and the report changed to: "freeswitch: rc_send_server: no reply from RADIUS server FQDN:1646, XXX.XXX.XXX.XXX" After that I increased the amount of retries in mod_xml_radius and then my Radius server (BTW is a Radiator) logged messages like the next one: "INFO: Duplicate request id 53 received from XXX.XXX.XXX.XX(42430): retransmit reply" If I run tcpdump in my Freeswitch server I can see every reply retransmited from the Radius server. It looks like that Radius Client can't process those replies. What else can I check? Regards, On 02-09-2016 14:20, Juan Pablo Godoy wrote:
Hello,
I was wrong yesterday Sergey, as you say the problem could be related to reverse resolv.
I've discovered that in Debian those errors are reported in /var/log/users.log and that the problem perhaps is the rate of calls, therefore could be related to the rate that my system tries to do the reverse resolv.
I don't think the problem is my DNS server, anyway right now I'm using google's DNS with the same results.
What could be limiting that rate? Is there a way to fix it?
Best Regards, Juan Pablo Godoy.

Hello Sergey,
Thank you very much for your help.
Please correct me if I'm wrong, but I don't think this is related to my DNS because my configuration don't use hostnames. Besides now that I'm using Debian I don't see those "look up" message anymore.
Best Regards, Juan Pablo Godoy.

It is look like DNS not return reverse resolv results. Please check DNS requests and responses.

Hello,
Can anybody help me please?
During this week I changed from CentOS 7 to Debian 8.5 and I still have the same problem. Honestly I don't know what to do anymore.

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.
