Hello,

yes - there is a crash happening. And you should consider doing an update, this version is really out of date.

Cheers,

Henning

Hey you log prints that there is a segmentation fault happening, maybe that’s your problem.

Hi All,

We currently experience issues where scscf hangs randomly throughout the day. It started hanging once in a month, the issue has gotten worse over time and now it can hang more than 5 times in a day.

I have no prior kamailio experience or experience debugging c applications.

Kamailio version: 4.4.0

Running ps shows scscf processes are running. Service status also shows scscf is running but it does not respond to sip requests.

Testing with sipsack hangs and print timeout errors.

root@NGVI-PCSCF2:/var/log # service scscf status

• Status of Kamailio SIP Server:
• scscf is running

sipsak -vv -s sip:NGVI-PCSCF2:6060

received ICMP message received ICMP message** timeout after 500 ms**

Below is the extract from log files
