-------------------------------------------

The logs are absolutely massive and there is nothing of interest at the exact time of crash, however, I've attempted to extract what is relevant and corresponding to the fax calls.

> After upgrading to 16.1.0, Asterisk crashed six times in the space of an hour. After downgrading to 13.24.0, it has been rock solid for a number of days. Prior to that it was on 13.23.1 and rock solid for weeks.
> I cannot isolate which component is causing the issue, however, the one possible area in which this server is unique (versus another similar server that is running stable on 16.1.0) is that it uses res_odbc and func_odbc extensively. But blaming those components would be speculative.
> I have attached two backtraces from two different crash events.
