New subject: 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.

I have tried using two different drivers for Cassandra in python but same
results.

I wonder if i import mysql driver kamailio starts perfectly.

Below it my script.

#!/usr/bin/python
import sys
import pymysql
*import pycassa*
from Router.Logger import LM_ERR
from Router.Logger import LM_INFO

class test:
    def __init__(self):
        LM_INFO('test.__init__\n')

    def child_init(self, y):
        LM_INFO('test.child_init(%d)\n' % y)
        return 0

    def handler(self, msg):
        LM_INFO('test.handler(%s)\n' % (msg.Type))
        if msg.Type == 'SIP_REQUEST':
            if msg.Method == 'INVITE':
                LM_INFO("Re-writing RURI")
                msg.rewrite_ruri('sip:0022@192.168.2.24:5073')
            LM_INFO('SIP request, method = %s, RURI = %s, From = %s\n' %
(msg.Method, msg.RURI, msg.getHeader('from')))
            LM_INFO('received from %s:%d\n' % msg.src_address)
        return 1

def mod_init():
    return test()

Any help is much appreciated.

Best Regards,
