Asterisk 1.8.4 and Queues (SIPP testing)

Nearly 2 days of Asterisk 1.8.4 testing give me some results:
In my projects i often use Queue app and test much it:
Testing was using sipp

extensions.conf

[code][sipp]
exten => _X.,1,Answer
same => n,Playback(hello-world)
same => n,Queue(test-queue)

[test]
exten => _[1234]X,1,NoOp
same => n,SayDigits(4713)
same => n,MusicOnHold

exten => _[5678]X,1,SayDigits(0548)
same => n,MusicOnHold [/code]

queues.conf

[code][test-queue]
strategy=random
setinterfacevar=yes

member = Local/01@test

member = Local/80@test[/code]

Nearly after 251 succesfull call I’ve got this errors:

[May 24 14:40:55] WARNING[21913]: channel.c:1454 __ast_queue_frame: Unable to write to alert pipe on Local/24@test-7ad7;1 (qlen = 69): Resource temporarily unavailable! [May 24 14:40:55] WARNING[21925]: channel.c:1426 __ast_queue_frame: Exceptionally long voice queue length queuing to Local/38@test-39a5;1
They are repeated continiously, just changing channel names. Calls are fails. Even when stop sipp, errors still generates.

So the question: what additional information must be posted in bugtracker?

PS: Also, I’ve done little simplier tests, I can post it here too.

The issue reporting guidelines are here:

asterisk.org/developers/bug-guidelines

The more information you can provide in the report, the better.

Cheers.
