[SR-Users] Segfault in dialog.so with 4.4.2 stable

Hi, Running Kamailio on Debian from the Kamailio repository with 4.4.2 stable (unpatched). Getting some random segfaults with it now, here's the relevant backtrace from the generated core. Core was generated by `/usr/sbin/kamailio -f /etc/kamailio/kamailio.cfg -P /var/run/kamailio/kamailio.'. Program terminated with signal 11, Segmentation fault. #0 run_dlg_callbacks (type=type@entry=64, dlg=dlg@entry=0x7fceb400e2f0, req=req@entry=0x7fced4f093c8, rpl=rpl@entry=0x0, dir=<optimized out>, dlg_data=dlg_data@entry=0x0) at dlg_cb.c:253 253 if ( (cb->types)&type ) { (gdb) bt #0 run_dlg_callbacks (type=type@entry=64, dlg=dlg@entry=0x7fceb400e2f0, req=req@entry=0x7fced4f093c8, rpl=rpl@entry=0x0, dir=<optimized out>, dlg_data=dlg_data@entry=0x0) at dlg_cb.c:253 #1 0x00007fcead3648f9 in dlg_terminated (dir=<optimized out>, dlg=0x7fceb400e2f0, req=0x7fced4f093c8) at dlg_handlers.c:368 #2 dlg_onroute (req=0x7fced4f093c8, route_params=<optimized out>, param=<optimized out>) at dlg_handlers.c:1354 #3 0x00007fceb10ab0e2 in run_rr_callbacks (req=req@entry=0x7fced4f093c8, rr_param=rr_param@entry=0x7fceb12b77a0) at rr_cb.c:96 #4 0x00007fceb10952c5 in after_loose (_m=0x7fced4f093c8, preloaded=0) at loose.c:919 #5 0x000000000042b618 in do_action (h=h@entry=0x7ffeb0b3ed80, a=a@entry=0x7fced4cb4338, msg=msg@entry=0x7fced4f093c8) at action.c:1060 #6 0x000000000042a10a in run_actions (h=h@entry=0x7ffeb0b3ed80, a=0x7fced4cb4338, msg=0x7fced4f093c8) at action.c:1549 #7 0x0000000000437544 in run_actions_safe (h=h@entry=0x7ffeb0b402b0, a=<optimized out>, msg=<optimized out>) at action.c:1614 #8 0x000000000053b2e8 in rval_get_int (h=0x7ffeb0b402b0, msg=<optimized out>, i=0x7ffeb0b3f1e0, rv=rv@entry=0x7fced4cb4d58, cache=cache@entry=0x0) at rvalue.c:912 #9 0x000000000054261c in rval_expr_eval_int (h=h@entry=0x7ffeb0b402b0, msg=msg@entry=0x7fced4f093c8, res=res@entry=0x7ffeb0b3f1e0, rve=rve@entry=0x7fced4cb4d50) at rvalue.c:1910 #10 0x000000000042bc91 in do_action (h=h@entry=0x7ffeb0b402b0, a=a@entry=0x7fced4cb8f88, msg=msg@entry=0x7fced4f093c8) at action.c:1030 #11 0x000000000042a10a in run_actions (h=h@entry=0x7ffeb0b402b0, a=0x7fced4cb8f88, msg=msg@entry=0x7fced4f093c8) at action.c:1549 #12 0x000000000042bcf2 in do_action (h=h@entry=0x7ffeb0b402b0, a=a@entry=0x7fced4cb91e8, msg=msg@entry=0x7fced4f093c8) at action.c:1049 #13 0x000000000042a10a in run_actions (h=h@entry=0x7ffeb0b402b0, a=0x7fced4cb3f48, msg=msg@entry=0x7fced4f093c8) at action.c:1549 #14 0x000000000042bde0 in do_action (h=h@entry=0x7ffeb0b402b0, a=a@entry=0x7fced4ac3d70, msg=msg@entry=0x7fced4f093c8) at action.c:678 #15 0x000000000042a10a in run_actions (h=h@entry=0x7ffeb0b402b0, a=a@entry=0x7fced4ac1698, msg=msg@entry=0x7fced4f093c8) at action.c:1549 #16 0x00000000004375d0 in run_top_route (a=0x7fced4ac1698, msg=msg@entry=0x7fced4f093c8, c=c@entry=0x0) at action.c:1635 #17 0x0000000000504386 in receive_msg (buf=<optimized out>, len=<optimized out>, rcv_info=<optimized out>) at receive.c:240 #18 0x00000000005f5bd4 in udp_rcv_loop () at udp_server.c:495 #19 0x00000000004b2625 in main_loop () at main.c:1600 #20 0x0000000000427e2b in main (argc=<optimized out>, argv=<optimized out>) at main.c:2616 And from syslog the relevant messages before this dump: Jul 15 08:55:03 server /usr/sbin/kamailio[16470]: WARNING: dialog [dlg_handlers.c:1219]: dlg_onroute(): unable to find dialog for BYE with route param 'd4c.26d1' [3149:7522] Jul 15 08:56:01 server /usr/sbin/kamailio[16481]: WARNING: dialog [dlg_handlers.c:1219]: dlg_onroute(): unable to find dialog for BYE with route param 'fc.99f1' [207:8089] Jul 15 08:56:27 server /usr/sbin/kamailio[16470]: CRITICAL: dialog [dlg_timer.c:200]: update_dlg_timer(): Trying to update a bogus dlg tl=0x7fceb3f7d920 tl->next=(nil) tl->prev=(nil) Jul 15 08:56:27 server /usr/sbin/kamailio[16470]: ERROR: dialog [dlg_handlers.c:1377]: dlg_onroute(): failed to update dialog lifetime Jul 15 08:57:01 server /usr/sbin/kamailio[16482]: ERROR: db_mysql [km_dbase.c:128]: db_mysql_submit_query(): driver error on query: Duplicate entry '9584-3854-435' for key 'hash_index' (1062) Jul 15 08:57:01 server /usr/sbin/kamailio[16482]: ERROR: <core> [db_query.c:181]: db_do_raw_query(): error while submitting query Jul 15 08:57:01 server /usr/sbin/kamailio[16482]: ERROR: sqlops [sql_api.c:265]: sql_do_query(): cannot do the query [INSERT INTO `dialog_extra` (`h_i] Jul 15 08:57:01 server /usr/sbin/kamailio[16482]: ERROR: auth [api.c:119]: auth_check_hdr_md5(): auth:pre_auth: Credentials are not filled properly Jul 15 08:57:01 server /usr/sbin/kamailio[16483]: ERROR: auth [api.c:119]: auth_check_hdr_md5(): auth:pre_auth: Credentials are not filled properly Jul 15 08:57:54 server /usr/sbin/kamailio[16506]: NOTICE: dialog [dlg_hash.c:245]: dlg_clean_run(): dialog in delete state is too old (0x7fceb3f64470 ref 4) Jul 15 08:57:54 server /usr/sbin/kamailio[16473]: WARNING: dialog [dlg_handlers.c:1348]: dlg_onroute(): inconsitent dlg timer data on dlg 0x7fceb3f64470 [1182:5803] with clid '09ad128753e2535d24bde58e3d7eda04@192.168.10.232:5060' and tags 'as1b497b34' '5788890C-EC6F55F-3E86ED0C' Jul 15 08:57:54 server /usr/sbin/kamailio[16469]: ERROR: dialog [dlg_handlers.c:334]: dlg_terminated_confirmed(): failed to get dialog from params!
