Summary:                    [patch] problem with ringinuse=no, queue members
receive sometimes two calls
Description: 
Dear all

on a debian amd64 i've installed (from source) asterisk 1.4.31

On the system we have in average 50 concurrent calls in queue and 40
sip members.

I'm experiencing an apparently random problem:
sometimes some users receive 2 calls from asterisk, apparently
ignoring the ringinuse=no settings.
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.

Any idea?
Why the call is still dispatched to the user if it is not in the "Not
in use" status?

i've added some customized log in the ring_entry function and this is the
result:

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)

Do you have any idea about what can cause that?

This is an example of my config

[PL1009]
context=mycontext
callerid=PhoneLine1009 <1009>
secret=pwd1009
type=peer
host=dynamic
call-limit=3
disallow=all
allow=ulaw

queues:
[queue_1]
weight=10
wrapuptime=0
strategy=leastrecent
joinempty=no
retry=0
autopause=yes
setinterfacevar=yes
eventwhencalled=yes
eventmemberstatus=yes
ringinuse=no

member => SIP/PL1009

[queue_2]
weight=10
wrapuptime=0
strategy=leastrecent
joinempty=no
retry=0
autopause=yes
setinterfacevar=yes
eventwhencalled=yes
eventmemberstatus=yes
ringinuse=no

member => SIP/PL1009


[queue_3]
weight=10
wrapuptime=0
strategy=leastrecent
joinempty=no
retry=0
autopause=yes
setinterfacevar=yes
eventwhencalled=yes
eventmemberstatus=yes
ringinuse=no

member => SIP/PL1009
