Lables keep disappearing

[AlexDark]

Hello, I've updated fop2 to 2.29 and encountered a problem.
Whenever I reload fop2 or just after a period of time all extension lables (except one, dunno why) disappear.
In fop2admin I can see that lables but fop2 doesn't show them, just their numbers.
What might be the problem?
(I am using russian letters)

What happens if you mouse over the button empty label, do you see it in a tooltip? How are your labels composed? Multiple words? Are they very long?

[AlexDark]

It's not empty, label shows extension number, but yes, I can see a tooltip, it's exactly the same.
Usually it's just a name. You can see 5 letters name at screenshot (the one that not disappears). There are more 5 letter names, so it's not the reason.
And I've just tested one more thing, english labels disappear too. Also, could it be related to my previous question - ?

Then the label does not disappear, but changes to 1003? That most probably means that the extension was added to a queue as a member with the member name 1003. FOP2 renames labels to member names when they are added to a queue.

Well, labels at admin page had never changed, and also there are only 3 extensions in queues, other 20 change with them.

When you add a queue member, the label on the manager has no relevance at all. If you want to trace the issue, you will have to start fop2 in debug mode and capture events, and look for "rename" events and what happens BEFORE you see those.

service fop2 stop
cd /usr/local/fop2
script capture.log
./fop2_server -X 511
(log into fop2, wait for the label renaming/change)
ctrl-C
exit
service fop2 start

Now you have a capture.log file to check for.

Best regards,
