[SR-Users] Kamailio crash

Tue Nov 27 13:33:38 CET 2012

Hello Daniel.

Thanks for the patch, we’re going to pull the patch and see how it Works.

I did’t see anything else I the syslog.  That was my first part to look for.

I will have updated about this issue.

Thanks!

Ricardo.-

Hello,

it seems that either callid parameter was not provided or couldn't be read
from the mi command? Have you got any error message in syslog before the
crash?

I pushed a patch that does a safety check in order to be sure that callid
parameter has a value. You have to take the latest version of the branch.

Cheers,
Daniel

Hello,

ahh, my mistake - the frame number is 1, do:

frame 1
p callid
p *callid

Yes.

Every 5 minutes we run a script to drop calls in state “3”.

Could be this the problem?

Could be cause, but should not be a problem.

In gdb, can you do:

frame 2
p callid
p *callid

and send the output?

The crash seem to happen when processing the callid value given via MI
command.

Cheers,
Daniel

Hello,

do you have any external application sending MI commands to terminate
active calls?

Just checking to be sure it is not a core file overwrite situation.

Daniel

I’m using kamailio

[root at pxh ~]# kamailio -V

version: kamailio 3.2.3 (x86_64/linux) 2a00c6-dirty

with dialog module, hash tables, radius authorization.

Hope someone could help me.
