Thanks, I will look over it and try to reproduce in the lab, it may take a bit since I am pretty much time offline these days.

Can you add a second rule and see what happens? At the first sight of the debug messages, the result from database is ok, should not be a null value there.

Cheers,
Daniel

Hello

I'd like to do some tests with the dialplan module, but Kamailio is crashing when it loads it. Actually the module is properly loaded if the table is empty, but it fails when a row is added; so I guess it's related with the way I've inserted the values. A core file is generated:

Core was generated by `./kamailio -f ../etc/kamailio/kamailio.cfg'.

Program terminated with signal 11, Segmentation fault.

#0 build_rule (values=0x0) at dp_db.c:439

439 new_rule->dpid = VAL_INT(values);

this looks a bit strange at first sight, 'values' parameter is NULL and should not happen. Besides that, in build_rule() functions there are other uses of 'values' before line 439, so the crash should have been earlier.

Please send full backtrace of the core, in gdb, run 'bt' command (or better 'bt full').

Also, if this reproducible, run:

./kamailio -f ../etc/kamailio/kamailio.cfg -E -dddd

and send the output.

Cheers,
Daniel
This is the relevant config:

#----- dialplan params ---

modparam("dialplan", "db_url", "mysql://xxxx:yyyyy@localhost/db")

modparam("dialplan", "table_name", "dialplan")

modparam("dialplan", "dpid_col", "dpid")

modparam("dialplan", "attrs_pvar", "$avp(s:dp_attrs)")

mysql> describe dialplan;

+-----------+------------------+------+-----+---------+----------------+

mysql> select * from dialplan;

+----+------+----+----------+-----------+-----------+-----------+----------+-------+

1 row in set (0.00 sec)

I'm probably making some stupid mistake...any clue?

Thanks in advance
