> Hello,
>  
> We are randomly experiencing freezes in what it seems app_queue. It manifests itself with not letting new calls entering any queue, no new calls passed to the agents. Existing calls work just fine i.e. already ongoing.
>  
> Typing in cli “queue show X” locks the CLI.
> Only way to release the issue to restart asterisk with “systemctl restart asterisk” for an example.
>  
> For Incoming calls passed through AGI this is the last we see for each call

> Yes, the last line is empty after chan_sip.c, the call gets no further.
> We are not sure to replicate this and it occurs sporadically. When it occurs, what measures can I do to capture more information? We cannot run Asterisk in debug mode if it impacts performance as this issue can take weeks to occur again.
> Am putting this as a Minor, as we do not know yet what is causing it.
