Hi Daniel,

Kamailio had only been running for about 24 hours with very little traffic on that server. Should we wait for longer and throw some calls at it?

Thanks again.

Hello,

on a second check, those counter chunks for counters/statistics seems to be from startup, thus not part of a leak.

How long have you been running kamailio? Looking at the pkg stats from previous email, the free part is still a lot, with only about 200k used. It could mean the leak was not making any effect yet.

Cheers,
Daniel

Hello,

the leak is due to keep defining counters or statistics. That should happen only at startup, but if you execute from perl script some function from a kamailio module, it may trigger this issue. Can you share what functions from kamailio are you execute inside the perl script?

Cheers,
Daniel

Hi Daniel,

Thank you - I used the restart method and got a whole load of memory information. 10 megabytes of it! I've compressed that and attached it to this email.

Thanks for your help.

Hello,

ahh, right, forgot that it was disabled because it was not safe to use at runtime for worker processes. You have to use:

kamcmd cfg.set_now_int core mem_dump_pkg <pid>

then wait for a bit so that process is receiving a SIP message.

Or, if you restart, the stats are printed in syslog for all processes.

Another alternative is to call pkg_status() or pkg_summary() from cfgutils module in config file, like:

if(src_ip==127.0.0.1 && is_method("OPTIONS") && $rU=="pkgstats") {
  send_reply("200", "OK");
  pkg_summary();
  exit;
}

You can use sipsak to send an options request to "sip:pkgstats@..."

Cheers,
Daniel

Hi Daniel,

When I send SIGUSR1 to a worker process nothing is logged. Any ideas there? The following is the output of "sercmd pkg.stats".

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

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.
