GC Collector Error shut down ingest node

[Emiliano_Baum]

The elastic service shut down when the log report the following error.
I use ES 5.6, over Ubuntu server 16.04. The cluster have 10 nodes, two of this are ingestion nodes, and one of this have the problem.
this is the service log:

Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; disabled; vendor preset: enabled)
   Active: failed (Result: signal) since Tue 2018-09-18 22:00:33 UTC; 13h ago

and this is the log of the application:

Can you post most of the log, there's nothing there that suggests that the node was shutdown.

Hi warkholm, the elastic log don't say to much, only the lines i pasted before. The service status said the proccess was killed at the same time the elastic log report the overhead warning.
This error could be caused for a lot of querys to the node?

I have two dedicated ingestion nodes that mainly receive indexing messages. To monitor the cluster, I use "Cerebro", and I suspect that the problem is due to this software, because yesterday I lowered the refresh rate and until now the cluster does not report problems
