Hi all,

we got a core in dialog module. We are using kamailio 3.1.2. Below you can find a full backtrace from the dump and the Kamailio compilation options. Please, if you need further information don't hesitate to ask me for it.  I can't precise the situation when it is generated because we have a quite high load in this server.

Thanks in advance.
Antón
