Kampolis Ioannis updated ASTERISK-23998:
----------------------------------------

    Status: Waiting for Feedback  (was: Waiting for Feedback)

Sorry for the late reply - I am on holidays.
I had a colleague - who will probably reply back if you need anything else for the next 7-10 days - prepare me a VM. We used Elastix 2.4 in this VM.

I attach a full .tgz of /etc/asterisk.

Queue 702 has three members: ext 3301,3302,3311.
Queue 703 has one member for this example 3304.
All extensions are sip extensions.
One the SIP phone 3304 I use unconditional call forward to queue 702 
For the call forward I did not use the feature code (*72), I just enabled it on the phone.
Then I use a simple code (stressdialer.tgz) to start sending calls to 703 by creating call files. Depending on the CPU it takes different number of simultaneous calls for the problem to appear.
In this case (VM with 2 cores - 2/4 of a Core 2 Quad Q8400)  10 simultaneous queue calls were required for the problem to appear.

> Two Queues:
> Queue 703 has one member 3304.
> Queue 702 has three members ()
> Once 3304 forwards (not using the asterisk feature code) all his calls to 702 a warning is issued channel.c: Exceptionally long voice queue length queuing to Local making the system unresponsive.
> This causes load more than 9 to a monster dual-cpu DELL R520 in a production environment with more than 20k calls per day. The issue is resolved once the call is terminated or with a restart of the pbx.
