I wrote a if condition below this line to know where dtp->prev

ok, you didn't say and it didn't match the sources.<br>
<br>
Hopefully the issue is fixed, you have to upgrade to latest git
branch 3.1 to get the fix:<br>

Some guidelines how to install from git are provided at:<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>

<div bgcolor="#FFFFFF" text="#000000"> 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>

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>
