Hi, Rodrigo!


Valgrind may report some memory allocated, and not freed, but that is not necessarily a memory leak. There is a single block of 1024 bytes not freed during runtime, so I think that is peanuts. The memory used by OpenSIPS is not allocated with malloc, so cannot be traced by valgrind.

Regarding the system memory, it is normal to decrease as OpenSIPS uses that memory during runtime. However, after some time, this should  stabilize. Anyhow, sometimes the system memory might generate false alarms, so if you are tracing any memory leaks, you should check OpenSIPS's internal statistics.

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:

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.
