Re: [SR-Users] Kamailio 4.0.4 slow memory leak

It is not needed to see the memory operations logs. Just to dump the chunks in memory.
You would need ctl and ctl_rpc modules (iirc -- they should be in the default config file), then run: 

kamcmd cfg.set_now_int core mem_dump_shm 1

Extract the logs of the dump from the shared memory and send them over.

Send also the output for:

kamctl mi get_statistics shmem:

Thank you.


I have recompiled with MEMDBG, however I am not observing any 
additional output in my log files.


I think I have something set incorrectly in kamailio.cfg.

Here are my log settings from Kamailio.cfg

debug=3

log_stderror=no

log_facility=LOG_LOCAL0

memdbg=2

memlog=2

…

modparam("debugger", "cfgtrace", 1)

modparam("debugger", "log_level", 2)

modparam("debugger", "cfgpkgcheck", 1)

modparam("debugger", "mod_level", "core=2")

modparam("debugger", "mod_level", "tm=2")

modparam("debugger", "mod_level", "dispatcher=2")

modparam("debugger", "mod_level", "siptrace=2")

Hello,


I quickly looked over the modules that use shared memory and I 
couldn't spot a commit related to any leak.


Have you had the chance to compile with  MEMDBG?

Cheers,
Daniel

    Hi Daniel,

    Here’s a list of the modules I’m running:

    mi_fifo

    db_mysql

    sl

    kex

    tm

    tmx

    rr

    xlog

    maxfwd

    usrloc

    registrar

    textops

    pv

    acc

    permissions

    siputils

    auth

    lcr

    dispatcher

    sanity

    debugger

    siptrace

    We’re setting the memory allocation to 256 ( -m 256 –M 64 ).

    I’ll see about recompiling with MEMDBG=1.

    Regards,

    - Tim

    Hello,

    can you give the list of loaded modules? How much memory did you
    allocate (-m parameter value)?

    It will narrow down searches to see if there was anything similar
    fixed since 4.0.4.

    To troubleshoot easier, would be good to recompile with MEMDBG=1,
    then the details of chunks in memory can be dumped and analysed.

    Cheers,
    Daniel

        Greetings,

        I’m running into a slow memory leak on my kamailio 4.0.4 SIP
        proxies. I’m observing a steady increase in the memory
        consumption until there is no more left. Kamailio then starts
        repeating this in the logs:

        ERROR: dispatcher [dispatch.c:279]: add_dest2list(): no more
        memory.

        What would be the best way to debug this kind of a memory
        leak? The proxy does not handle any registrations but does
        route a fair amount of calls.

        Thank you in advance,
