[SR-Users] Core dump on diameter CCR request

Hi all, I am trying to implement Diameter charging with Kamailio. I am following below tutorial https://www.kamailio.org/events/2016-KamailioWorld/Day2/15-Carsten.Bock-Dia… But whenever I try to do the Ro_CCR from the INVITE block, Kamailio is crashing and generating the core dump. I am new to diameter. I might be doing something wrong here. please someone help me here. Please find the *diameter.xml* and *Diameter_core_dump_full_debug.txt* file. diameter.xml <http://sip-router.1086192.n5.nabble.com/file/t6374/diameter.xml> Diameter_core_dump_full_Debug.txt <http://sip-router.1086192.n5.nabble.com/file/t6374/Diameter_core_dump_full_Debug.txt> Here is my kamailio.cfg : loadmodule "cdp" loadmodule "cdp_avp" loadmodule "ims_charging" loadmodule "ims_dialog" modparam("cdp","config_file","/etc/kamailio/diameter.xml") modparam("cdp", "debug_heavy", 1) # ----- ims_diameter_ro params ----- #modparam("ims_charging", "single_ro_session_per_dialog", 1) modparam("ims_charging", "origin_host", "10.195.0.38"); modparam("ims_charging", "origin_realm", "10.195.0.38"); modparam("ims_charging", "destination_realm", "mydomain.com"); modparam("ims_charging","interim_update_credits",30); modparam("ims_charging","timer_buffer",5); # -- ims_dialog params -- modparam("ims_dialog", "dlg_flag", 8) While starting the kamailio, i am getting following errors: Nov 11 11:40:03 ip-10-195-0-38 /usr/local/sbin/kamailio[25653]: ERROR: cdp [peerstatemachine.c:675]: add_peer_application(): Too many applications for this peer (max 0), not adding Application 4:0.
