[Kamailio-Users] kamailio / deadlock3

[Aymeric Moizard]

Got some more info:

The UDP deadlock always seems to happen after a SUBSCRIBE
is sent (in UDP) to mobipouce.com:

Jan 28 11:00:40 ns26829 /usr/sbin/kamailio[13363]: ERROR:core:tcp_blocking_connect: poll error: flags 18
Jan 28 11:00:40 ns26829 /usr/sbin/kamailio[13363]: ERROR:core:tcp_blocking_connect: failed to retrieve SO_ERROR (111) Connection refused
Jan 28 11:00:40 ns26829 /usr/sbin/kamailio[13363]: ERROR:core:tcpconn_connect: tcp_blocking_connect failed
Jan 28 11:00:40 ns26829 /usr/sbin/kamailio[13363]: ERROR:core:tcp_send: connect failed
Jan 28 11:00:40 ns26829 /usr/sbin/kamailio[13363]: ERROR:tm:msg_send: tcp_send failed
Jan 28 11:00:40 ns26829 /usr/sbin/kamailio[13363]: ERROR:tm:t_forward_nonack: sending request failed

This logs happens each time I got a SUSCRIBE being relayed to another 
server: mobipouce.com. But the deadlock doesn't appear each time.

mobipouce.com is an existing & running server where I can connect with UDP 
and TCP. However, the SRV record returns 2 host where one host is down.
(and I never got reply for the SUBSCRIBE: either if it fall into deadlock 
cas or not)

In case I can reproduce what step could I take to get more information 
about the issue? Any kmctl command?
