RabbitMQ server crashing - rabbitmq

Question

Version - rabbitMQ : 3.9.11, Erlang : 24.3.4.1
We are using nodejs process to publish and consume.
All of a sudden RabbitMQ stops responding. Even the web page would not respond (Dashboard).
Usage / RAM / queue sizes are normal at the time of crash.
If we see the log at crash time we got this:

We are not getting any exception on our node process. It keeps publishing.
Please Help us to diagnose and solve the issue
Thank you.
We try to diagnose using rabbitmq-diagnostics cluster_status, but we are not getting any response from the server.
Server won't respond until we restart the service.
