Hello,

you can place any new modules in old version of kamailio, but they were not tested and not supported officially by the project. Anyhow, if you get an issue with a new public module, likely it is in the master branch as well and we will fix it if you provide the backtrace when it happens again.

The statsd module is now in master branch of Kamailio repository, you don't need to take it from eloycoto repository. Eloy is maintaining it in Kamailio project as well.

Cheers,
Daniel

Hi Daniel, thanks for your prompt response. I read the module's GitHub readme and there it says that it can be installed with 4.2:

Fetch kamailio code:

git clone --depth 1 --no-single-branch git://git.sip-router.org/kamailio kamailio
cd kamailio
git checkout -b 4.2 origin/4.2

Add the module:

git submodule add https://github.com/eloycoto/statsd modules/statsd
git submodule update

Compile the module:

make include_modules="statsd" cfg
make

I can't reproduce it, it happened only once last Friday and I've monitored the system over the weekend and didn't happen again... I checked the logs (/var/log/messages and /var/log/kamailio.log) and I don't see any other messages for PID 21149. What I did is enable the CORE Dump after the issue so that now if it happens again I can have it.

Thanks!

Federico

Subject: Re: [SR-Users] Kamailio 4.2.4 segfault and crash

Hello,

I see you have statsd module, but that is not part of the 4.2.x series. Have you backport that?

Can you reproduce it? Or it happened once?

Also, the error logs after crash are not that relevant, can you see what log messages were printed by PID 21149 before the crash?

Cheers,
Daniel

Hi all, I just experienced a sudden crash from one of my Kamailio servers. I'm using v4.2.4 built from git repository (branch remotes/origin/4.2). The error logs show this at the time of the crash (I'm using debug=1 on config file)

The modules I'm using are:


loadmodule "mi_fifo.so"
loadmodule "db_mysql.so"
loadmodule "sqlops.so"
loadmodule "tm.so"
loadmodule "sl.so"
loadmodule "pv.so"
loadmodule "xlog.so"
loadmodule "maxfwd.so"
loadmodule "siputils.so"
loadmodule "sanity.so"
loadmodule "textops.so"
loadmodule "rr.so"
loadmodule "statsd.so"


Have you noticed this error before? This server has a very simple config, for every invite received, it queries a MySQL database to replace the called number from 3 digits to 8-10 digits (for example 135 is translated to 1152751135) and sends back a 300 Redirect with the new number. 


Another thing to notice is that this server was working at 3-4% CPU load and when the issue happen it spiked to 53%...


Let me know I can provide any other info that could be useful.


Thanks!


Federico
