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

Hello,

ok, so that was...

Maybe it would be good to add a note to the docs of the module about this issue so people become aware of it. I guess the other http_* modules are affected. Pull requests or other suggestions are welcome, of course!

Cheers,
Daniel

Hi Daniel,

Thank you a lot, it looks that issue is solved, after updating libcurl.

I was using following manual for updating libcurl, in case if somebody will have same issue.

Hi Daniel,

You are correct we are using heavily http_query.

I found following bug report:

https://bugs.centos.org/view.php?id=9391

I will try to update to libcurl 7.44 and check if this help.

Thank you a lot Daniel!

With kind regards,

Hello,

from the logs, it seems to be related to curl library, I see many reports like:

That's like almost 200KB lost in this report.

From the list of the modules, I see you have utils and I guess you use http query function from there, is it?

Cheers,
Daniel

Hi Daniel,

I left valgrind running for little while, not sure if this will be enough.

Please find attached log file.

Thank you a lot for your help!

With kind regards,

Hello,

that's the way it was done for older versions of kamailio.

In master and 4.4 the memory debugging is turned on and it is reflected by the presence of DBG_SR_MEMORY in the output of 'kamailio -v'.

Anyhow, what you reported is not a leak inside kamailio memory manager, but a leak of using system memory, so it is not affected by DBG_SR_MEMORY and cannot be troubleshooted using the mechanisms for pkg and shm managers.

Cheers,
Daniel
