Hi Callum,
Sorry for the late follow-up: did you make any progress with your leak?
If not, could you prepare a minimal opensips.cfg that exposes the
problem? A quick
code review did not show any obvious leaks, so I suspect there is something
about your specific script that I am overlooking.
Best regards,

Hi All,
I wanted to follow up on a recent issue I experienced to understand if
it was due to user error or a bug that needs to be patched.
The issue was traced back to a simple function call in the permissions module:
check_source_address(0, $avp(address_desc))
Nearly every request processed would have been an unlisted source
address and a negative response would have been expected. As an in
memory hash lookup for a small address list (<50 records) this seemed
like a very safe operation to perform.
The AVP is uninitialised at the point of invocation - I am guessing
that this is key to the problem. To resolve the problem I have simply
removed the AVP and the method call is now:
check_source_address(0)
I would like to learn whether using an AVP for this operation was
incorrect or whether there was another reason for the leak. I've had a
go at reviewing the source for permissions and pvar however I quickly
got lost trying to find where the AVP initialisation would have been
invoked. Any advice would be appreciated.
Many thanks,
Callum
