[SR-Users] rtpproxy 1.2.1 segfaults with kamailio 3.2.2 in bridging mode

[Karsten Horsmann]

Hi all,


i try to register at the rtpproxy mailinglist, but its still pending.
Maybe someone here had the same issue.
In my multihomed setup (with mhomed=1 in kamailio.cfg) i had segfaults
from rtpproxy if i called rtpproxy_manage with params.

Notice that i must run rtpproxy as root to get core files.

Any hints? Maybe my kamailio config isnt right?

ulimit -c unlimited ; /usr/local/bin/rtpproxy -u root -s
/home/sys/bin/rtpproxy.sock -l <PUBLIC-IP> 172.20.100.74 -d
