Hi, I just updated a test server from FS 1.10.6 to 1.10.7 on Debian 10 (apt update/upgrade from the official repo) and without changing anything on my config I got a buffer overflow when running "/usr/bin/freeswitch -u freeswitch -g freeswitch -c -nonat ": *** buffer overflow detected ***: /usr/bin/freeswitch terminated Aborted I tried the original modules.xml that comes with the package and it starts up without problems. Doing a bit of trial & error with my modules.conf.xml I noticed that the problema is with the mod_event_multicast module. Loading it from modules.conf.xml or by doing “load mod_event_multicast” result in a crash. This is the current module: # sha1sum /usr/lib/freeswitch/mod/mod_event_multicast.so 4daee6fa8ae8ed59c5ebc32393cb7357fead8198 /usr/lib/freeswitch/mod/mod_event_multicast.so Overwriting the module with the 1.10.6 one seems to work: freeswitch@pbx.mydomain <mailto:freeswitch@pbx.mydomain>.com> load mod_event_multicast +OK Reloading XML +OK 2021-10-28 14:21:23.038592 96.17% [CONSOLE] switch_loadable_module.c:1768 Successfully Loaded [mod_event_multicast] 2021-10-28 14:21:23.038592 96.17% [NOTICE] switch_loadable_module.c:389 Adding API Function 'multicast_peers' but even with the module loaded the events aren't being sent to my other server, my event_multicast_conf.xml is this: <configuration name="event_multicast.conf" description="Multicast Event"> <settings> <param name="address" value="225.1.1.1"/> <param name="port" value="4242"/> <param name="bindings" value="CUSTOM sofia::register"/> <param name="ttl" value="1"/> <!-- <param name="loopback" value="no"/>--> <!-- Uncomment this to enable pre-shared key encryption on the packets. --> <!-- For this option to work, you'll need to have the openssl development --> <!-- headers installed when you ran ./configure --> <param name="psk" value=“pbx.mydomain.com"/> </settings> </configuration> I don’t see any multicast traffic being sent from this server nor the " Propagating registration for….” message. Any idea what can be happening? Thanks! ======================================== Koldo Aingeru Marcos Fdez.
