[OpenSIPS-Users] Leak AVPOS + SQLITE

[Rodrigo Pimenta Carvalho]

Hi.


Does someone here is getting/handling memory leaks with OpenSIPS 2.2 and last version of SQLite?

I'm using newest commit from OpenSIPS 2.2 and newest version of SQLite.


My query is :


avp_db_query("select Value from GeneralConfigurations where Attribute = 'CONFIGURATION_INTERCOM_A_NAME'");


Valgrind shows:


==16087== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 2 from 2)

==16088== Reachable blocks (those to which a pointer was found) are not shown.

==16088== To see them, rerun with: --leak-check=full --show-leak-kinds=all



After some time running that query, I can see, via command top, that the available memory is decreasing.

In fact, the memory is not freed even after stop running the query for a time.


Best regards.
