    Assignee: N A  (was: Unassigned)
      Status: Waiting for Feedback  (was: Triage)

Yes, it shows that it's in the handle_chanlist function. For example, though, the given line number doesn't match 18.9.0. An actual backtrace would better confirm things and show more information.

> Currently, Asterisk crashes randomly every few days, not seemingly linked to anything going on at the moment. In fact, prior to this crash, the system was completely idle (no calls) for the previous 34 minutes.
> Here is a backtrace from right before the last crash, useful as it has line numbers:
