[Spce-user] Kamailio-lb core dump

[John Murray]

Hello,

 

I have upgraded to V2.7 and now kamailio-lb process dumps core when calls
come in from a PBX:

 

Jan  7 18:04:43 skt-salem03 /usr/sbin/kamailio[10401]: ALERT: <core>
[main.c:785]: child process 10402 exited by a signal 11

Jan  7 18:04:43 skt-salem03 /usr/sbin/kamailio[10432]: : <core>
[pass_fd.c:293]: ERROR: receive_fd: EOF on 12

Jan  7 18:04:43 skt-salem03 /usr/sbin/kamailio[10401]: ALERT: <core>
[main.c:788]: core was generated

Jan  7 18:04:43 skt-salem03 /usr/sbin/kamailio[10401]: INFO: <core>
[main.c:800]: INFO: terminating due to SIGCHLD

 

If I restart the kamailio-lb service it works again fine until a call comes
in from that PBX.

 

It looks like since 2.7, 200 OK messages have a different 'Contact:' format
with the addition of 'ngcpct':

 

Contact: <sip:ngcp-lb at 100.100.100.183:5060;ngcpct='sip:127.0.0.1:5080'>

 

The PBX replies with an ACK:

 

ACK sip:ngcp-lb at 100.100.100.183:5060 SIP/2.0'

 

Which I think is missing the 'ngcpct' part so doesn't match and the OK ->
ACK cycle is repeated a few times until the call is torn down.

Is there a way to disable this new 'ngcpct' part until I can get the PBX
vendor to fix it?

However it seems a problem that the kamailio-lb process stops when this
happens as of course all other calls on the system stop.

Is there any way to fix this?

 

Best regards

 

John
