Thanks Lonnie

Unfortunately the response I received Josh on the Asterisk forum was that he 
was sick of spending time chasing things that were already fixed and that I 
needed a backtrace to look any deeper. I do understand his position but that 
doesn't help us that much.

I'm not quite sure where to take it from here other than to use the non SE 
version of Astlinux and see if it fixes the problem.
PS I have another customer who is using an IVR with queueing and there are no 
issues. They don't get as many calls as the problem site and may not do what 
triggers the crash but they are on a later version of Asterisk (13.23.1) so 
that could be the reason. Hard to work out.

    Michael,
    
    If Asterisk 13.25 works for you we can try to find the related patch and 
apply it to the 'se' 13.23.1.
    
    Possibly you can followup your forum question to pinpoint which commit(s) 
fix the issue.

system (log messages only) when using a different dialplan setup of cascading 
queues. At the time I suspected that I was having issues with ASTERISK-27006 
and after reverting the Asterisk version to 13.14.1, (thanks Lonnie for helping 
with this), the problem went away. Since then I have changed the dialplan back 
to a standard single queue setup and have upgraded to Astlinux 1.3.2 (Asterisk 
13.18.5) and I suspect that I am experiencing the same bug.

queue via a Local Channel. This could be the reason why this bug may be coming 
into play again.
