What could be causing these errors to occur? They specifically happen overnight when no one is around.

I allocated more memory to Elasticsearch by following http://stackoverflow.com/questions/18132719/how-to-change-elasticsearch-max-memory-size (2GB up from default 1GB)

Are you seeing this error in the browser or the Kibana logs?

Which version of Kibana is this, and do you have a reverse proxy in between the browser and the Kibana server?

Hi,

I am seeing this error in the browser while having the dashboard open. Although like I mentioned before the errors happen overnight. I experience no issues while using it during office hours.

We are using Kibana 4.4.0 and indeed have a reverse proxy in between the browser and the Kibana server.

Could it be because every night a new indice/index is being created and on top of that data of the last 24 hours is being loaded as it refreshes every hour?

Some thoughts are the proxy has become unavailable, or it's unable to route the request to Kibana. I would look into the proxy logs in addition to Kibana's to see if it's being restarted due to something like an upstart script.
