Hi All, I have a basic proxy up and running for over 6 months without issue, had a random crash, not sure why. Restarted kamailio process and it's working as expected. Any clue is the log to indicate what might have happened? ----snip---- Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13416]: : <core> [mem/q_malloc.c:468]: qm_free(): BUG: qm_free: freeing already freed pointer (0x7fa1e1ebd658), called from <core>: mem/shm_mem.c: sh_realloc(88), first free <core>: mem/shm_mem.c: sh_realloc(88) - aborting Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13415]: ALERT: <core> [main.c:775]: handle_sigs(): child process 13416 exited by a signal 6 Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13415]: ALERT: <core> [main.c:778]: handle_sigs(): core was not generated Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13415]: INFO: <core> [main.c:790]: handle_sigs(): INFO: terminating due to SIGCHLD Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13423]: INFO: <core> [main.c:841]: sig_usr(): INFO: signal 15 received Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13420]: INFO: <core> [main.c:841]: sig_usr(): INFO: signal 15 received Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13424]: INFO: <core> [main.c:841]: sig_usr(): INFO: signal 15 received Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13419]: INFO: <core> [main.c:841]: sig_usr(): INFO: signal 15 received Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13421]: INFO: <core> [main.c:841]: sig_usr(): INFO: signal 15 received Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13422]: INFO: <core> [main.c:841]: sig_usr(): INFO: signal 15 received Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13418]: INFO: <core> [main.c:841]: sig_usr(): INFO: signal 15 received Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13417]: INFO: <core> [main.c:841]: sig_usr(): INFO: signal 15 received Jul 5 16:31:46 sip-router3-ve206 /usr/local/sbin/kamailio[13415]: ERROR: ctl [ctl.c:379]: mod_destroy(): ERROR: ctl: could not delete unix socket /tmp/kamailio_ctl: Operation not permitted (1) ----snip---- RTPProxy also running on the server was not affected. root@sip-router3-ve206:/var/log# kamailio -V version: kamailio 4.1.0 (x86_64/linux) 350d2e flags: STATS: Off, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 350d2e compiled on 16:41:38 Dec 17 2013 with gcc 4.4.5 Yes, I know it's an older version but I prefer not to upgrade unless absolutely necessary. I'm sure this was a random event, not too concerned but since it is a production server, I'm obligated to investigate. Thanks. JR -- JR Richardson Engineering for the Masses Chasing the Azeotrope
