Issue with more number of users connecting to multiple sessions

We have roughly 90 users connected through 3 sessions each having video and audio connected.
Users are logged in from multiple locations
Almost after 6 hours of multiple sessions we see this message coming up

"JVB 2020-02-27 19:18:17.455 WARNING: [813109] org.jitsi.videobridge.AbstractEndpointMessageTransport.log() Unable to find endpoint a19dc622 to send EndpointMessage"

This is usually followed by some info messages so we thought it will recover. But after half an hour these messages kept on coming up till and until we don’t restart services, after which it stabillizes for next 4/5 hours.

Are we missing any configuration?
These are the part of logs for reference
