I'm getting a connection refused when I run the git clone command:
# git clone --depth 1 --no-single-branch git://git.sip-router.org/kamailio kamailio
Cloning into 'kamailio'...
fatal: unable to connect to git.sip-router.org:

I'm using the tutorial on: https://www.kamailio.org/wiki/install/4.2.x/git

I'm running 4.2.3 from tar.
I'll try the git branch.

Hello,

one thing to clarify. Are you running v4.2.3 from packages/tarballs or from branch 4.2?

There was a fix to jsonrpc-s, already backported to branch 4.2 few weeks ago, but after release of 4.2.3.

If you don't run from git branch, can you install from there (or from debian nighty builds)? It might be same issue, so it is better to check that before further troubleshooting.

Cheers,
Daniel

Hello,

I understand. I'll get you the logs.
Yes, I did run the ulimit command.
Do I need to do anything else? Or get the logs from somewhere else?

Hello,

I need the logs printed by kamailio before the crash, to see what was processing at that time. After crash is no information in the logs printed by itself why it crashed .

The traces printed in syslog by the kernel are not easy to use for troubleshooting and I see the core was not generated to use gdb for a proper backtrace. Have you run 'ulimit -c unlimited'?

Cheers,
Daniel

Hello Daniel,

Yes, I can reproduce it every time I run those commands from within the script.

I've only included the trace(see attachment) from the point kamailio crashed, since it only happens when a certain condition inside the script is met. (if statement)
But when the condition is met, it crashes every time.

If you need more information, please let me know.

Regards,

Grant

Hello,

can you reproduce it every time you run those commands? Or is it happening from time to time?

If you can reproduce, set debug=3 and send all the logs to me. Also, it would be good to set 'ulimit -c unlimited' before starting kamailio to get a coredump which would be easier to troubleshoot.

Cheers,
Daniel

Hello,



Kamailio crashes when I try to execute the following jsonrpc_exec functions:



jsonrpc_exec('{"jsonrpc": "2.0", "method": "domain.reload", "id": 0}'); #domain module

jsonrpc_exec('{"jsonrpc": "2.0", "method": "addressReload", "id": 0}'); #permissions module



This one works fine:

jsonrpc_exec('{"jsonrpc": "2.0", "method": "htable.reload", "params": ["tablename"], "id": 0}');



Any ideas?



Running on Debian 7.8 and Kamailio 4.2.3.
