Kevin Harwell commented on ASTERISK-29116:
------------------------------------------
Please attach associated configuration files (sip.conf, confbridge.conf, etc..), or relevant sections from those.
Also please execute the {{ast_coredumper}} script [1] against the core file and/or running Asterisk at the time, and attach its output here.
Lastly, please attach a full Asterisk log with debug level 5 enabled if possible from an occurrence.

> Key: ASTERISK-29116
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-29116
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: PBX/General
> Affects Versions: 17.5.1
> Reporter: Dennis Haney
> Assignee: Unassigned
> Severity: Minor
>
> I have hundreds of threads stuck with this stack trace, which eventually causes the server to run out of resources and is unable to make further calls.
> I dont see any other threads with dl_open in the stack that isnt this, nor any other threads with pbx_thread that isnt stuck like this.
> FYI, we are stuck on chan_sip if that makes a difference.
