[SR-Users] Errors leading to kamailio proc crash

[Grant Bagdasarian]

Can I increase the shared memory when kamailio is still running or configure it somewhere in a configuration file to use x amount of shared memory? The kamailio process  is managed by heartbeat/pacemaker as a resource and I was advised not to manually restart a resource which is managed by heartbeat/pacemaker.

The virtual server Kamailio is running on is up for 133 days now. But the kamailio process was up for a couple of weeks, since it has been restarted a few times.

Where can I find the coredump?

Default shared memory is 32MB, that is quite low if you have a lot of traffic.

You can increase it with '-m' command line parameter.

Try to get a coredump and then send the backtrace. It will help to discover where is the issue, even when out of memory, there should be no crash. For that, use 'ulimit -c unlimited' before starting the sip server.

How long it was running? Can it be eventually reproduced?

Also, to be sure is not an issue already fixed, upgrade to latest 3.3.x, you don't have to change anything in database or config file.

Cheers,
Daniel

Hello,

Last Thursday our kamailio process crashed. There are a lot of memory related errors in there. See attachment for details.

Did the machine run out of memory? How do I prevent this from happening again?
The machine has 4GB of memory.

Regards,

Grant
