Hi everyone,
I believe I've run into a problem when using dlg_end_dlg (with mi_datagram ) called from an external perl script with perl_exec() .
Kamailio just locks after a while (few seconds) after disconnecting a call. Some parts of my debug log can be found here: http://pastebin.com/ANaTEifC
The problem was observed while performing a stress test. Is it a good idea to call dlg_end_dlg() like that or I can kill an established dialog from the routing script in some other way ?
Regards, Dragos
Hello,
does it block for few seconds and then goes on, or it locks after few seconds and stays locked?
If the second, attach with gdb to the pid of the locked process and get the backtrace.
Cheers, Daniel

Hi Daniel,
It locks and stays locked. It is interesting that for a while ( 1-2 minutes while I am sending some traffic ) it can reply to REGISTER with a 200 OK , but it does not reply `100 Trying` to INVITE . Then nothing, no reply. gdb output here: http://pastebin.com/Kg3hwzZT

Hello,
the backtrace is from the MI process, not a SIP worker. That process does not handle sip traffic.
Before you start testing you can do 'kamctl ps' and see which are the sip workers and get the backtrace from those pids.

Hi
Yes, Daniel , you are right.
Here is a backtrace from a SIP worker: http://pastebin.com/t6XPQ6dx

Hello,
the backtrace shows that the process is blocked inside perl script listing on the network. Perhaps is waiting the reply to the command sent to kamailio. Perhaps the perl functions you are using in your script can have a timeout and not block forever.
In which case you need to terminate the call in config? There is a dlg_bye() function that could be useful.
Cheers, Daniel
