             Summary: Asterisk sudden crashes with segmentation fault

          Issue Type: Bug
      Security Level: None
          Components: . I did not set the category correctly.
    Affects Versions: 15.4.0
         Environment: Ubuntu Linux 16.04 ( kernel 4.4.0-1077-aws)
            Reporter: Cyril Ramière


Hello everyone,

I am badly needing help about an issue with our asterisk.

We are on asterisk 15.4.0, we made no changes on the system or the configuration (asterisk.conf, pjsip.conf...) and we tend to get occasional crashes with segmentation faults.

I'm really strugling to know what happends because there are no "warning signs" before a crash happen, it works and then it just dies.

There are nothing useful in the system logs (just the line telling that there was a segmentation fault).

We are using asterisk in realtime mode for all of our calls with MySQL, and everything is handled through the ARI interface (no static dialplans) connected to our application.

I attached the logs (messages), kern log, and the crash dump.

I know that asterisk is compiled without debug flags and is optimized, this is a critical, production machine.

I am unable to reproduce the issue, it just happened twice il a month causing huge troubles for us (there were more than 800 channels active, recordings on some, moh, webrtc sessions...).

Running asterisk without optimizations & with better traces seems not an option since it sucks so much more ressources, I'm 100% sure that our hardware couldn't handle it.

I'm begging for help, anything where I can start ?
Is there something I can do?

Best regards.
