Re: [SR-Users] Kamailio Process CPU 100%

Hi Team, Facing 100% Kamilio CPU issue, here are the details, any pointers/hints would help. Thanks *Scenario:* Random Kamailio CPU shoot, restart fixes it. Happens once or twice in a day. It's a pre-production server with around 30 extensions, not much load. For now, it has 2 CPUs and 4 G memory. *[Info]* uname -a Linux ip-X-aws #46-Ubuntu SMP Thu Jul 4 13:38:28 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux kamailio -V version: kamailio 5.2.3 (x86_64/linux) c36229 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, 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_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: c36229 *(gdb) bt full* #0 0x00007f0069d97aab in ??
