<p>Hello,</p>
<p>can you send the backtrace with gdb from the core file? The logs
say the corefile was generated -- it should beeiter in / or in the
workind directory you set for kamailio.</p>
<p>Cheers,<br>
Daniel<br>

<div>Dear list<br>
<br>
</div>
Im quite new to Kamailio and i found something while trying
to see the failover behaviour in Kamailio. I have a kamailio
v4.3.5 load balancing two Asterisk boxes.<br>
<br>
</div>
This happens just when i stop one of the asterisk and make a
call that is being load balanced to the same asterisk box that
i stopped before, when trying to go to failure_route and
dispatch it to the other box then Kamailio just crashes. I
have debug=4 in the config file and it really doesnt say much
about the error. This is the relative logging i could found:<br>

<div>It may be a bug in that Kamailio version because i used
Kamailio v4.2 before and i didnt have that inconvenient,
still i had to upgrade to v4.3 because i needed the
default_socket modparam that wasnt implemented in Kamailio
v4.2<br>
<br>
</div>
<div>Any hint about this issue would be appreciate it<br>
