Unable to start Kibana and [circuit_breaking_exception]

[Wilks]

Hi,
I am unable to start KIbana 7.2. I get the following message in the browser

"{"statusCode":429,"error":"Too Many Requests","message":"[circuit_breaking_exception] [parent] Data too large, data for [<http_request>] would be [1021976864/974.6mb], which is larger than the limit of [1003493785/957mb], real usage: [1021976864/974.6mb], new bytes reserved: [0/0b], with { bytes_wanted=1021976864 & bytes_limit=1003493785 & durability="PERMANENT" }"}"

I have tried killing the PID, stopping and restarting services and even a full system reboot but I cant seem to get it to start up.

Any thoughts?
thanks

@Wilks,

This error is coming from Elasticsearch. What is the state of your cluster right now?

Can you hit Elasticsearch directly? What goes GET _cluster/health report?

When you said you did a full system restart, did that include Elasticsearch as well, or just Kibana? Can you try restarting your cluster?

[Wilks]

Full restart of underlying OS. So a flat out reboot of the Linux system. I will give that a try

[Wilks]

Restarted but still no go......the KIbana service never starts up, I mean it starts up for a second and then immediately shuts down..

I see a similar error here: Get [parent] Data too large from kibana logs

Based on that post, do you know which garbage collector you're using with Elasticsearch? Changing to CMS instead of G1GC might help
