Asterisk Team commented on ASTERISK-28643:
------------------------------------------

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.

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.

>          Issue Type: Bug
>      Security Level: None
>          Components: PBX/General
>    Affects Versions: 16.6.1
>         Environment: Centos 6.10
>            Reporter: Steve Sether
>            Severity: Critical

> Asterisk creates a deadlock, and stops responding to any SIP messages when I park a call. No new incoming calls are accepted, no outgoing calls are accepted, etc.  Some initial investigation using gdb and the core file show this might indicate it's related to generating STATUS messages from the AMI.  This happened when only one or maybe two calls were on the system.
> I was able to reproduce it initially a couple times, (and got some debug information out of it, including from a version where core show locks was compiled in).  For whatever reason, I can't seem to reproduce it again, even under the same conditions.
