      Status: Waiting for Feedback  (was: Triage)

Unfortunately there's no obvious sign as to what's causing the crash in the thread1 file, and the other files that would have the thread information don't have anything in them.
If it's possible to get logs leading up to the crash, that would be nice to have (although I know these can get rather large over time). If it crashes again, save the core dump itself just in case we end up needing to take a look at that. Is this a system used in production, or a test system that would be possible to make changes to if needed to debug the issue?

> 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.
