[SR-Users] RTPProxy incorrect port 0 in reply from rtp proxy

[Grant Bagdasarian]

Hello,

I've been load testing kamailio(4.2) with rtpproxy(2.0) using sipp, and when I hit 50+ CPS I start getting the following error: "incorrect port 0 in reply from rtp proxy".
I'm running 4 instances of rtpproxy on the same instance as kamailio.

Could somebody tell me why I'm receiving this error? Do I need to run more instances of rtpproxy?

# <#----------RTPPROXY Parameters----------#>
modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7721 udp:127.0.0.1:7722 udp:127.0.0.1:7723 udp:127.0.0.1:7724")

In request_route:
                if (is_method("INVITE")) {
                               record_route();

                               if (has_body("application/sdp")) {
                                               rtpproxy_manage();
                               }
                }

In onreply_route:

                if (has_body("application/sdp")) {
                               rtpproxy_manage();
                }
