Some Warning and Error in Videobridge Log

Hi,

I installed this conference app for about 1 year, and it is very nice.

So last year we only use this conference tool in small groups and it is just fine, no complain. After some time, my colleagues use this conference too, so there are many user use this. i get a report that there are some error screen or disconnect problem like this one:

i cannot re-produce the problem. everytime i try it its just fine. i’m guessing it is happen on busy hour and to random user. The resource is like this:

cpu & ram usage in jitsi-meet web server is still low
cpu usage in jitsi-videobridge is still around 20%, ram is 40-50%. Bandiwdth(UL + DL) around 50Mbps

here is some log i get on jitsi videobridge

Many warning and some error, is that actually ok? (i dont know is it related to the error screenshoot earlier or not)

I don’t tweak my server too much just some editing on the jitsi-meet html and static file. The configuration of jicofo, prosody and jitsi videobridge is common.
