Summary:                    Core dump during normal usage of queues
Description: 
The queues server hosts two queues, and the calls are sent to these queues
via SIP. There's a fair amount of DTMF usage in here. autofill set in
queues.conf. One queue transfers the first SIP transferred calls to the
other queue.

And this server was doing its thing when asterisk crashed. All agents
complained that they got "kicked off by the system"

Another core has been dumped. Asterisk kicked all users out of the queue
(might have even restarted, does it?) 

Core was generated by `/usr/sbin/asterisk -f -vvvg -c'.
Program terminated with signal 11, Segmentation fault.

duration=100) at
channel.c:2480
2480            if (chan->tech->send_digit_end)

The new backtraces are being uploaded.

Please note: 
At this time, and all times, htop reports that CPU 4 is the most used one.
When all agents are logged on, the usage of CPU 4 is above 95% whereas the
other 3 CPUs are hardly used. The max one of those 3 CPUs goes up to is
probably 2%. If I could figure out how to make Asterisk use all these 4
CPUs that would be great.
