Elastic crash, nodes timed out

Elastic Stack Elasticsearch

Hi. I have an elastic cluster on Kubernetes. Since yesterday I am facing the problem of kubernetes nodes stopping.
3 nodes (64GB RAM)

The last logs it reads before crashing are:

Anyone know where I can look for the reason that the cluster stops responding/responding after a very long time?

Okay I consider the problem solved. It turned out that the problem was that I was uploading a corrupted file through File Data Visualizer and this was causing these errors and then a timeout on the node.
