[asterisk-bugs] [JIRA] (ASTERISK-16115) [patch] problem with ringinuse=no, queue members receive sometimes two calls

Tue Feb 25 13:00:07 CST 2014

    [ https://issues.asterisk.org/jira/browse/ASTERISK-16115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=215649#comment-215649 ] 

Matt Jordan commented on ASTERISK-16115:
----------------------------------------

Nope, this was not solved by ASTERISK-22189.

This issue is still open because no one has proposed a patch that solves the issue. The issue here, fundamentally, is that the {{ringinuse}} option requires the global state of the queue member across all queues to be known. That requires locking all queues in order to get that state accurately, which (a) has massive performance implications, and (b) requires very careful usage of the locking in {{app_queue}} to avoid deadlocking the whole thing.

Until someone tackles that problem, this issue will remain open.

> It appears on users that are members of many queues
> As you can see from the log, the user goes in a status Ring+Inuse.

> It seems that the system does not change the status of the user after calling it, and then re-schedule a new call.
> After that the status is updated and goes in a ring+inuse status (7)

> I've tried:

> 1.4.30
> run the system using ESXi on DL380
> run the system using ESXi on HP Blade
> run the system directly on hardware without virtualization
> used slackware 13.0 instead of debian AMD 64
> changed the kernel hertz to 1000 instead of 250
> added dahdi to optimize timing
> On client-side, i've tested
> Sjphone on windows
> CISCO 7940 phone
> in all these test-case i had the problem, and it occurs with a frequency of 100 times each 4000 calls.
