Asterisk Crash seg fault

Hi There,

We have an asterisk server (ver 14.3.0) crash with folllowing log entries in syslog.

Any idea what caused this and how to avoid crash in future due to this error?

It occured only once so far.

Dec 23 15:31:40 ubuntu kernel: [532105.894950] show_signal_msg: 6 callbacks suppressed
Dec 23 15:31:40 ubuntu kernel: [532105.894966] asterisk[15797]: segfault at 10 ip 00007f1700bfd404 sp 00007f166c659fb0 error 4 in[7f1700bf3

See for how to get the information that would be the minimum to try to debug this.
