Description:Connected to Asterisk CLI via remote console

While working, connected to same Asterisk instance via another remote console over a separate SSH connection.

Executed "core restart now" on the new console. Returned to a CLI prompt with no other output. The secondary console (the one I'm on) becomes unresponsive completely. Any key press fails to result in a response.

On the original remote console, the console responds to many commands, but some are missing.

A tab tab of "core show .." shows these commands as possible:
{noformat}
rnewton-office-lab*CLI> core show
calls           channel         channels        channeltype     channeltypes    codec           codecs          config          help            locks          
taskprocessors  translation     uptime
{noformat}

We are missing "core show settings" "core show version", etc.

A "core stop now" or "core restart now" on the original console results in
{noformat}
Ignoring asterisk shutdown request, already in progress.
{noformat}
, but Asterisk does not end.

attaching backtrace (while running) and "core show locks" output

Can't reproduce... tried a second time and things restarted cleanly... Something must have got in a funky state before I tried the restart on the first instance of this freeze.

Attaching new trace from what appears to be a very similar freeze. Unfortunately this may not be useful as I had already recompiled without DEBUG_THREADS.

This time, a "core stop now" failed to end Asterisk. CLI shortly became unresponsive. Had to kill Asterisk's process to end it.

This looks similar to the other reports of things hanging - we do an unsubscribe and join from the CDR engine and that blocks something in Stasis.

It'd be good to get a 'core show locks' the next time this happens

Can you point another hanging issue? I haven't been able to find them.
Thanks

@Thomas this has been fixed in trunk. If you are testing with Trunk, update to the latest version.

Actually I'm using recent 1.8 versions.
Do you have a pointer to the issue or to the commit?
Thank you

@Thomas

Not sure.. It doesn't show up in the Subversion tab here.

I'd recommend testing with the latest 1.8 SVN branch and if that doesn't fix your problem then it's likely a new one..

I believe Matt Jordan made the fix. I'll ping him to see if he can point out which commit it was.

Turns out the fix wasn't related to anything in 1.8. If you have an issue in 1.8 and you think it is a bug, please file a new issue. https://wiki.asterisk.org/wiki/display/AST/Asterisk+Issue+Guidelines
