--------------------------------------------------------------
It happens two or three times per day, almost every day. Every asterisk instance runs inside a container so the environment is consistent between then. Different instances crash randomly, it's not always the same instance or instances running on the same node etc.

> This is a follow up for ASTERISK-28931, which we opened some time ago. Seems like the same problem is happening again.
> This problem occurs in versions as old as Asterisk 17.3.0 and is happening in every version onwards. We are currently running version 18.0.1 and the segfault still occurs.
> Our Asterisk instances are crashing at least one time per day and in some cases even multiple times, with the following backtrace being displayed:
