We have issue with constantly increasing of Old gen part in JVM heap on coordinator nodes till OOM.
As I can understand the issue - memory leaking\OOM precisely correlated with requests to ES
that generated by Kibana DevTool (when autocomplete enabled and Console used by admin)
In audit requests looks like
For some reasons such request is too heavy for our cluster
Is there any way to
Understand why this "standard Kibana" request so heavy for our cluster ?
( too many indecies? too many fields ? )
Understand why ES coordinator nodes never free memory filled with this requests result data ?
(old gen heap consumption grow till node OOM)
Disable autocomplete\refresh for all users of DevTools (including new) ?
(I tried to set kibana.autocompleteTerminateAfter=1 , but without any luck )
Any thoughts/advice would be great.
