[SR-Users] INFO: <core> [main.c:809]: sig_usr(): signal 15 received

Greetings Again List. After being unable to use ndb_cassandra with kamailio I tried to use app_python. Below is relevant configuration. version: kamailio 4.4.2 (x86_64/linux) 892ad6 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_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 892ad6 compiled on 07:50:03 Jul 1 2016 with gcc 4.9.2 modparam("app_python", "script_name", "/usr/local/kamailio/etc/kamailio/handler.py") request_route { ..... python_exec("handler"); ..... } And i am using example provided in app_python module. *But i soon as i import Cassandra driver in script*. Kamailio terminate with there logs.
