There is no problems without haproxy. And haproxy no problems without kamailio :)

I used tcpdump (can't attach here) to dump port 6380, so kamailio should connect to haproxy, because it send ping and receive pong.

Hi try first to use single redis for make sure that it is not a ha proxy trouble.

If error still exists - try to collect debug information.

Hello,

Kamailio after restart(or start) sometimes can't connect to redis (via haproxy) with logs:

Redis and haproxy working fine (I test it by many attepts - echo ping|ncat localhost 6380)

At tcpdump all attemps from kamailio have:

*1

$4

PING

+PONG

*2

$6

SELECT

$1

0

+OK



my kamailio 5.0.4 config:
modparam("ndb_redis", "server", "name=redis;addr=127.0.0.1;port=6380")

my haproxy 1.5 config:
backend bk_redis
        mode tcp
        option tcp-check
        tcp-check connect
        tcp-check send PING\r\n
        tcp-check expect string +PONG
        tcp-check send QUIT\r\n
        tcp-check expect string +OK
        server sipkazan 192.168.107.195:6379 check inter 1s
        server local 127.0.0.1:6379 check inter 1s backup
