Rustam Fayzullin commented on ASTERISK-29979:
---------------------------------------------

Core dump is now enabled, at least for the near future. The system is used in production. We have multiple asterisk instances with this issue.
I'll add that asterisks are used in docker containers, so I'll attach container config, if it matters.

> Asterisk randomly crashes with segmentation fault. Sometimes once a month, sometimes 2-3 times a week.
> We have over a 100 VMs with asterisk and the most loaded of them fall most often. Nothing suspicious was found in asterisk logs.
> Also we couldn't reproduce the crash.
