Hello,

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

==16459== 189,318 bytes in 167 blocks are possibly lost in loss record 681 of 683

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,

Jurijs

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
