What are the specs of your Jibri server?

It’s azure Standard_F8 8vcpus with 16 GB.
Server is running jitsi + jibri on same server.
There was only one room with 5 participants. I checked CPU usage was about 30% and only about 6GB ram used.

You can connect to Jibri desktop through vnc to check what is going on. This may be a videobridge issue since jibri cannot get the media
