More than 2 participants video and audio is not working

Hi All,

We have configured external js in our server. If more than 2 partitciapants connected audio and video is not working. If there only 2 participants it works fine if it is more than 2 it is not working. Same configuration works fine for production server. For testing it is not working . Here only the difference b/w production and test jitsi is capacity. For testing it is 4 GB for prod it is 8GB. Is capacity matters?
