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

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?
is it recovering itself or you have to restart? How much cpu usage you get?
I if one or many eating lot of cpu, then use gdb to attach to the pid of
process using lot of cpu and get the back trace:
gdb /path/to/kamailio pid
Cheers,
Daniel

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?
