Hello,

send SIGUSR1 to one of the worker processes (e.g., UDP listener). The main process of kamailio doesn't process SIP messages, so it is not exposed to leaks.

You can used 'kamcmd pkg.stats" to see statistics about usage of pkg  per each process (older versions have sercmd).

'kamctl ps' gives the list of processes.

Cheers,
Daniel

Hi Daniel,

What I copied and pasted is all that's listed when I do a kill -SIGUSR1 on the Kamailio master process. How do I get fuller logs?

Thanks for your help.

Hello,

you gave only the first part of memory log output. The chunks listed there are from startup, thus not part of a leak, because they are not allocated again at runtime.

Can you give the full logs with messages from qm_status? The leaks are typically listed towards the end of those messages.

Yesterday someone else reported a potential leak when using perl module, so it might be something else there. I found one, which is related to an error case, but perhaps you don't get that, otherwise you will notice the error message.

Cheers,
Daniel

Hello,

Following up on this after a long break. It seems we are still having a memory leak. We've added the memory debugging options as per the documentation with the following output.
I'm not sure how to read it though - can anyone help? Thank you.
