Hi Daniel,

I found modules what are impacted by this leak:

http_client
utils
xcap
http_async_client
auth_identity
xcap_client

I would like to update documentations, but this is first time when I'm
updating documentation.

I believe I need to update xml file for module. Should I then regenerate
readme file as stated here:

https://www.kamailio.org/wiki/devel/how-to/module-readme

Or not?

Then I believe to create pull request with my changes. Correct?

Maybe you have manual for this?

With kind regards,

Jurijs
