Problems with more than 20 participants in one ROOM

Hi everyone.

I know, its a recurrent question, but I have problems when 20 people connect at the same time.

I installed Jitsi on a 8Cores 64GB server on, on a fresh Ubuntu distro.

I tried two times connect more than 20 people at the same time, and it was impossible (everybody sees everybody). When the 21 or 22 gets in, after a while, he/she is kicked out. ¿What could be the reason?

The jitsi installation is fresh, from this sunday. I am quite confused. What could be the problem?

Do I need to add

JAVA_SYS_PROPS="-Dorg.jitsi.jicofo.MAX_SSRC_PER_USER=100 …"

in /etc/jitsi/jicofo/config, in the variable JAVA_SYS_PROPS ?

Seen here:

It’s not easy to get always 20 people for the testing…

I edited my file in /etc/prosody/conf.d and it contains now this

Component "" "muc"
    storage = "none"
    muc_max_occupants = 3
    modules_enabled = {
        -- "token_verification";

but I am able to connect with more than 3. I tried to limit to 3 people, so I can test it. (Found here:

Whats the difference between this and setting: “-Dorg.jitsi.jicofo.MAX_SSRC_PER_USER=3 …” ?
