[SR-Users] Kamailio Stop Responding Randomly

[Henning Westerholt]

Hello,

have also a look to the log messages if you get some hints why it stops processing.
The backtrace indicates some DMQ processing, I’d suggest that you update to the latest 5.4.x or (better) 5.5.x release.
There might be bugfixes that helps to mitigate the issues you are facing.

Cheers,

Henning

Subject: [SR-Users] Kamailio Stop Responding Randomly

Kamailio  first  gives timeout on ctl unix socket as I am exporting data using prometheus exporter,  after a few minutes it stops responding to any sip request  on default/production  udp port  binded with multiple IP addresses for sip traffic.

The other listing port which is used by keepalived check script   for  bing-pong keeps responding to option messages.

Its very random behaviour occurs after a few days or after a few months, the system having max load 350 concurrent calls with load average 200-300.

links of core dump files are shared below which are collected before restarting the process.
