Issue Description

Have recently started seeing a huge uptick in these crashes on Astrisk 20.5. Seems to be related to hangups, at least as far as I can tell, and with WebRTC clients.

This is becoming quite a mess for us with these crashes. Any way to get more helpful logging or debug for this? Log output when the crash happens is below.

Relevant log output

It will crash with a number of messages like this:

Realizing now this is probably related to #487 but after upgrading, it's nearly constant for us, even under very light load.

Does the additional BT info here help pinpoint the issue?

Not overly, but it looks to be the exact same thing as #487 at its core. I'd suggest putting the information on there. That issue has already been accepted, even without the additional information previously required.

I'm marking as a duplicate accordingly per my previous comment. Throw additional info over on that issue.
