We are using 4 dashboards in Kibana, of which 3 are working just fine. The 4th one however always crashes when loading more than the last 7 days. When loading the last 30 days, we get 1 or 2 'Error in visualization [esaggs] >' error, and a running beyond timeout notification which will be followed up with a timeout error. When loading for bigger periods of time, like the last year, the entire right side of the screen is filled with 'Error in visualization [esaggs] >' errors and the session times out and we get logged out of Kibana.
When opening one of these errors, no further information is given. The request time of the crashed visualization (the empty one, they don't all crash when loading below a year) will be something like 5700+ms. No scripted fields are used in the dashboards. We do however have 2 datatables which have rows split on 2 datafields, instead of 1. I figured this might be the issue, but the information is needed, so maybe there is a workaround?
Is there a way to fix this error, maybe by changing settings, optimizing the visualizations or scaling up our Kibana subscription?
