Asterisk Team commented on ASTERISK-30157:
------------------------------------------
Thanks for creating a report! The issue has entered the triage process. That means the issue will wait in this status until a Bug Marshal has an opportunity to review the issue. Once the issue has been reviewed you will receive comments regarding the next steps towards resolution. Please note that log messages and other files should not be sent to the Sangoma Asterisk Team unless explicitly asked for. All files should be placed on this issue in a sanitized fashion as needed.
A good first step is for you to review the [Asterisk Issue Guidelines|https://wiki.asterisk.org/wiki/display/AST/Asterisk+Issue+Guidelines] if you haven't already. The guidelines detail what is expected from an Asterisk issue report.
Then, if you are submitting a patch, please review the [Patch Contribution Process|https://wiki.asterisk.org/wiki/display/AST/Patch+Contribution+Process].
Please note that once your issue enters an open state it has been accepted. As Asterisk is an open source project there is no guarantee or timeframe on when your issue will be looked into. If you need expedient resolution you will need to find and pay a suitable developer. Asking for an update on your issue will not yield any progress on it and will not result in a response. All updates are posted to the issue when they occur.

> Key: ASTERISK-30157
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-30157
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Core/Bridging, Core/Channels
> Affects Versions: 18.9.0
> Reporter: N A
> Severity: Major
>
> This has happened several times now that I've begun to pick out a pattern of this deadlock consistently happening in the same place, so here we are:
> The deadlock is always on a channel (which then blocks the entire channels container), which basically grinds Asterisk to a halt as existing calls may complete but no new channels can be created.
> core show locks:
