Hi Guys,   We are running kamailio 4.4.6 on debian 8 and not had any issues, however we did suffer a segfault and a core was generated;   May 25 09:17:06 Kam-HA-1 /usr/sbin/kamailio[9560]: ALERT: <core> [main.c:740]: handle_sigs(): child process 9575 exited by a signal 11 May 25 09:17:06 Kam-HA-1 /usr/sbin/kamailio[9560]: ALERT: <core> [main.c:743]: handle_sigs(): core was generated May 25 09:17:06 Kam-HA-1 /usr/sbin/kamailio[9560]: INFO: <core> [main.c:755]: handle_sigs(): terminating due to SIGCHLD     Running gdb on the core file generated returns this output;     Reading symbols from /usr/sbin/kamailio...Reading symbols from /usr/lib/debug/.build-id/bc/fbd7e44c057e9e7e0680c2a5e8f6a47290c5ba.debug...done. done.
