we encountered a really strange issue today. Whenever
many participants (many = more than 20) joined a conference
it kept crashing with “Something went wrong” for all participants.
We got the crash on a Debian system with jitsi-meet package version 2.0.5390-3 and also
on another system with 2.0.5870-1. Both systems worked without problems before, but what
had changed? Nightly security updates by unattended-upgrades!

Preparing to unpack …/prosody_0.11.2-1+deb10u1_amd64.deb …
Unpacking prosody (0.11.2-1+deb10u1) over (0.11.2-1) …
Setting up prosody (0.11.2-1+deb10u1) …
Installing new version of config file /etc/prosody/prosody.cfg.lua …
So I downgraded prosody to the old version and problem is gone away.
There are many security changes in prosody 0.11.9 that were backported
to 0.11.2, including also rate limiting for client connections in
Would be nice if a Jitsi developer could inspect the changes
from 0.11.2-1 to 0.11.2-1+deb10u1. Maybe it is not only the rate
limit that is problematic, there are also changes in mod_bosh
with a new option c2s_stanza_size_limit.
