Hello,<br><br>I wrote a if condition below this line to know where dtp->prev was being initialized.<br><br>dtp = (dbt_table_p)shm_malloc(sizeof(dbt_table_t));<br><b>if (dtp->prev){<br> LM_DBG("dtp->prev was initialized")<br>
}</b><br><br>Analysing the trace of kamailio, the condition is true only to subscriber table. I can't get understand this behavior only subscriber table because to others tables (location, dispatcher and version) the condition is false.<br>
<br>PS: I'm doing this analysis to understand the core generated in db_text module described in the previous e-mails.<br><br>Best Regards <br><br><div class="gmail_quote">2011/10/3 Daniel-Constantin Mierla <span dir="ltr"><<a href="mailto:miconda@gmail.com">miconda@gmail.com</a>></span><br>

Hello,<br>
<br>
the latest 3.1 branch as in db_text/dbt_tb.c following line:<br>
<br>
dtp = (dbt_table_p)shm_malloc(sizeof(dbt_table_t));<br>
<br>
Where is the line you refer to dpt->prev? Can you copy&paste
it here.<br>
<br>
Cheers,<br>

Someone knows why at line 149 in .../kamailio-3.1.2/modules_k/
<div>db_text/dbt_tb.c the shm_malloc function sometimes
allocates memory to dtp->prev but sometimes doesn't?<br>
I'm asking this question because when the subscriber table is
being loading to shared memory in db_text module, dtp->prev
is allocated but on version, dispatcher, location table it
doesn't... Analysing the source code I can't see any reason to
this behavior.<br>
<br>
The allocation of dtp->prev to subscriber table is generating
a core at db_text module.<br>
<br>
