Hi, my Kibana instance seems to be encountering this internal server error from time to time. Does anyone know why?

```auto

This route is fetching the suggestions for the query bar. It is basically doing a terms aggregation. Can you check the Elasticsearch logs whether anything in there correlates with these errors?

Hi @flash1293,

Thanks for the response. I don't see much of anything in the logs. This is all it has which seems to be a few days old:

```auto
[2020-09-21T16:34:15,529][INFO][o.e.i.b.HierarchyCircuitBreakerService] [logs1] attempting to trigger G1GC due to high heap usage [6121484288]

```

But heap seems to be fine on all nodes (60-70%).

This doesn't seem related. Which version of Kibana are you running?

Both Elasticsearch and Kibana are on version 7.9.0.
