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?

Hi again people!
I'm currently having some trouble with my sip.antisip.com server.
Within the previous 2 or 3 days, kamailio sometimes fall into some kind of dead lock.
I've been checking my logs while the dead lock happen, and it seems (although I'm not sure with only the logs) that only UDP support is broken: I can see some TLS and TCP registrations but do not see the usual udp traffic (keep alive for example)
Any idea?
