[OpenSIPS-Devel] Out of pkg mem with own module

[Schumann Sebastian]

Hi Bogdan

I am not sure, but I figured the problem must come from my module. And I have only two times where I use pkg_malloc and both look like the snip.

I will try to debug it, let's see if I will be successful. Thanks for this direction.
