Re: [SR-Users] Memory leak in 3.3.4

2 Oct 2013

      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,
