Hello,

I wrote a if condition below this line to know where dtp->prev was being initialized.

dtp = (dbt_table_p)shm_malloc(sizeof(dbt_table_t));
if (dtp->prev){
     LM_DBG("dtp->prev was initialized")
}

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.

PS: I'm doing this analysis to understand the core generated in db_text module described in the previous e-mails.

Best Regards

Hello,

the latest 3.1 branch as in db_text/dbt_tb.c following line:

    dtp = (dbt_table_p)shm_malloc(sizeof(dbt_table_t));

Where is the line you refer to dpt->prev? Can you copy&paste it here.

Cheers,
Daniel

Hello ALL,

Someone knows why at line 149 in .../kamailio-3.1.2/modules_k/
db_text/dbt_tb.c the shm_malloc function sometimes allocates memory to dtp->prev but sometimes doesn't?
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.

The allocation of dtp->prev to subscriber table is generating a core at db_text module.

Best Regards
