---------------------------------------------
I am experiencing the same problem and I have been able to replicated the fault:
Connected to Asterisk 13.11.2 currently running on localhost (pid = 30307)
-- Got SIP response 302 "Moved Temporarily" back from 192.168.97.71:5060
-- Now forwarding DAHDI/i1/0871350000-1 to 'Local/444 at internal' (thanks to SIP/4000-00000000)
[2016-09-16 14:49:44] NOTICE[30388][C-00000001]: core_local.c:740 local_call: No such extension/context 444 at internal while calling Local channel

> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Applications/app_queue
> Affects Versions: 13.6.0, 13.7.2
> Environment: Debian 8.3 amd64
> Reporter: Etienne Lessard

> Given I have a queue with 1 member: Alice (SIP/alice)
> Given Alice's phone has a forward (SIP native) to the 444 extension, and the 444 extension isn't defined in the dialplan
> When Bob calls the queue
> Then asterisk get stuck in what seems to be an infinite loop, consuming a lot of CPU time, and rapidly consuming (in the matter of seconds) all the available memory in the system, until the kernel OOM killer terminate the process
> In my example, I used the following queues.conf:
> {code}
> [sales]
> strategy = ringall
> member => SIP/alice
> {code}
> And the following extensions.conf:
> {code}
> [default]
> exten = 101,1,NoOp()
> same = n,Queue(sales)
> same = n,Hangup()
> {code}
> When Alice's phone receives a SIP INVITE from asterisk, since it has an unconditional forward enabled, it respond with a "302 Moved Temporarily" with the header "Contact: <sip:444 at 10.34.1.11>".
> I've attached the interesting part of the log.
> Thank you
