Ghost users remain after people leaving the room

Hello!

I’ve been seeing this situation in which after someone leaves a room it still ‘remains present’ but it is actually not there, and so, if the same person reconnects, then it appears duplicated.

Has someone ever seen something like this?

It started happening a few days back, it did not happen before, i did no other changes other than the maximmum alocated ram for jvb and jicofo.

thanks!

This happen if the person login backe before 10 seconds.
Just remove the extra user or say him to reload the page with CTRL+SHIFT+R

Sadly this didn’t work. The ghost user remains whether the person behind it reconnects or not.

And it happened mutiple times within the same session since connection problems with the participants networks are not that stable.

Do you have any other information about this?

Thanks!

Which browser are they using?
Are you sure they don’t open another browser window?

As far as I know, we always -and strongly- recommend using Google Chrome or Chromium-based browers; most of them use Google’s. When it fails, we recommend to use the app.

It has happened randomly in both scenarios, app and computer w/ chrome.

Thank you!

This is a really strange behaviour

I really don’t know what could make this happen

Hi Jitsi team!

We do experience the same issue. Sometimes our users use a room in the span of several days and as a result there are sometimes 5-6 ghosts just hanging around and one of them is the room admin, so we cant even kick out those ghosts.

These ghosts are usually appearing after a user is being disconnected (mobile or browser) without explicitly leaving the room.

We have a vanilla/quick install on Ubuntu 18.04 installation.

Please let us know if we can help you with debugging.

Thank you!

I have seen that one time too with Jitsi Android (bad 3G connection). Out of curiosity, when you have the problem, does a new user joining the room see these ghosts ?

In our case it does, the rejoined user does see both, itself and its ghost user.

That seems to be the case, when suddenly disconnecting but not explicitly leaving the room.

That would be awesome. What can I do for it?

Thanks.

sorry I said a new user, not the user having been turned in a ‘ghost’

Oh, sorry, I will look that up. Thx

In testenvironment (“me” and “second me”) - once happened, now after each room creation (from RocketChat) a new one… Ofcourse not kickable, because all “moderators”.

Prosody 0.11.4

jitsi-ghosts

Hello,

We have the same issue and sending a message into the chat refreshes the participants.

Configuration & context:
jitsi-meet 2.0.4548-1
jitsi-meet-prosody 1.0.4074-1
jitsi-meet-web 1.0.4074-1
jitsi-meet-web-config 1.0.4074-1
jicofo 1.0-567-1
prosody 0.11.2-1

The prosody storage is set to « memory », the secure domain is set.
Apache is used (not nginx)

We have around 700 participants at the same time on 4 jvb2 when it occurs and we used chat and sharing into the « bugged » rooms (don’t know if it is a pattern)

I’ve done yesterday update to prosody 0.11.5 (Debian repo) and Ghosts are gone.

I was about to open a new post then I found this post seems describing my issue.

I found if the jitsi client (browser, desktop applications) closed abnormally (for example on Windows Ctrl+Alt+del then end jitsi by killing the process, or the participants disconnect because of poor connection), that user will stay in the room forever. Next time I enter the same room, the previous me is there and I can’t kick it out because the current me is not the host. I can replicate the issue on meet.jit.si as well.

Hello, I opened a new post yesterday because I still have the issue. I don’t know if you have the same behaviour:
