Kevin Harwell commented on ASTERISK-28472:
------------------------------------------

Hrm, this is a tough one especially since it happens sporadically.

1. Can you think of anything that changed just before noticing the crash? For instance, had you upgraded Asterisk, or libsrtp?

2. It looks like a channel is attempting to join a bridge. Please post the relevant dialplan, and endpoint(s) configuration for the call.

3. Speaking of endpoints, what kind of endpoints/phones are used in the crash scenario? Is that something that changed recently, and then you started seeing the crash?

4. Please attach the Asterisk log leading up to the crash (even better if debug 5 is enabled but understand not wanting to enable debugging for an extended period if this is a production system).

5. Lastly, if you can, install srtp with debug symbols. The crash occurred down in the library itself. Those symbols might help show what/where it was actually crashing on.

> We're seeing this crash every now and then - last time was around 3 weeks ago, on Asterisk 16.3, though we've upgraded to 16.4 since then, and enabled BETTER_BACKTRACES and DONT_OPTIMIZED to try and get to the bottom of it.
> I'm at a loss for what might be causing it. When this server crashed it was serving 6 channels, and the only exotic thing being used by any of them were ARI, but I don't believe any of the active channels were actually in the Stasis application.
> I'm not really qualified to read the crash dump, but there is some mention of libsrtp in one of the files, so I've included which version of that we're using (1.5.4, as recommended on the wiki).
> Any insight would be greatly appreciated, and I can provide whatever else information might be valuable.
