Hi,
Just add something my colleague forgot to mention and i think it may help.
This error happened after the phone sends a subscribe (or was it a
publish?) message with a strange event package = presence.winfo (or
something like this).
The reaction of presence module (out of my head, so could be wrong) is
to answer with a 484 Event package not known ...
Then, after a while, a timer gets called which tries to clean the
active watchers table ... and then ... pum! :) the seg fault here
attached ...
As you can see in the bt, the problem seems to be in strlen call ...
probably the row_vals returned is null (?) ... and strlen I think is
not very robust against this sort of perversions :)
610 subs.event_id.len =
strlen(row_vals[event_id_col].val.str_val.s);
Cesc
PS - The work around seems to be to start openser with a clean
(=empty) active_watchers dbtext file ...

Hi,
I'm trying to use db_text database with the presence module of
OpenSER(1.2.x).
User agent is X-Lite(3.0). When I try to send a REGISTER message to OpenSER,
OpenSER still works.
But if i sent a SUBSCRIBE or a PUBLISH message, then openser crashes.
If i use the MySQL database, then everything works just fine. But i prefer
to use the db_text database.
Here is the core file that was generated when OpenSER crashed.

I really hope that someone can help me with this problem. Thanks in advance.
