Segmentation Fault - Asterisk will not start

Asterisk Asterisk Support

After updating from asterisk 15 this lovely system decided it could no longer run. I am hoping the community has a bit of advice on getting this back online again.

This was a dist upgrade from Stretch to Buster and an Asterisk version 15 to 16.2.1

As a work around I attempted to reinstall asterisk and it yielded this…

I would clear out ‘astmoddir’ and recompile.

If that still fails, I would delete anything that ‘find / -xdev | grep --ignore-case asterisk’ shows and re-install from scratch.

4

using “apt remove asterisk” I removed it from the system then used the original 15.6.2 source dir to recompile what was there. That worked and its back online again. I am still wanting to get it updated only this time I will not be doing it in the middle of a work day when people rely on the server. I take full responsibility for that one. Lesson learned!!

Telephony is one of those things that isn’t perceived as all that important until it isn’t there.

A ‘dev’ environment where you can load your production dialplan and make a test call, even on a VM, can save a lot of heartache.
