Disappeared queue members

[manakamanana]

Hello,

We have Asterisk 11.9.0, FOP 2.28 and 4 queues:
all - 10-15 members
fir - 7-10 members
sec - 1-3 members
thi - 1-3 members

Add queue member format(816 ext it's for example):
AddQueueMember(all,Local/816@from-queues/n,0,,,hint:q816@subscribe)

peer 816 placed in context from-internal

Button settings:
[SIP/816]
type=extension
extension=816
label=name cc
mailbox=816@default
context=from-internal
queuecontext=from-queues

[QUEUE/all]
type=queue
extension=all
label=
context=from-internal

Sometimes members from queue 'all' and 'fir' just disappeared from panel and after some time back again. In such moments queues all and fir, or only all, or only fir looks empty. What does it depend on? Maybe it's configure issue?

What is the output from

asterisk -rx "queue show"

On those moments you see the queue members empty in fop2 ? Anyways, try to always set a label for fop2 buttons instead of leaving it empty, an empty label in a button will actually disable it.

At this moment in fop2 queues all and fir looks empty, but queues sec and thi still looks fine.
Changing label did not help.

I do not see any reason for that to happen, unless there is some kind of misconfiguration or odd configuration (like monitoring multiple servers with same queue names, perhaps a problem with case/lower/upper mismatch).

The way to tell is kind of complicated as you will need to start fop2 in debug mode and look at the manager events just in the moment you see a queue button show empty members (not sooner, nor later, as the log will be huge and hard to follow).

To start fop2 in debug mode interactively (so you can stop it when the error happens), you can do this:

service fop2 stop
cd /usr/local/fop2
script capture.log
./fop2_server -X 511

You will see lots of things flowing on the screen. Log into fop2 and monitor your queue buttons, once you notice a queue button show no members, do this:

ctrl-C
exit
service fop2 start

You will end up with a capture.log file that will let us inspect/analyze what could go wrong.

Problem resolved, it was an extra character in member name. Thanks for your help!
