I have many Java microservices running in a Kubernetes Cluster. All of them are APM agents sending data to an APM server in our Elastic Cloud Cluster.
Everything was working fine but suddenly every microservice received the error below showed in the logs.
I tried to restart the cluster, increase the hardware power and I tried to follow the hints but with no success.
Obs: The disk is almost empty and the memory usage is ok.
Everthing is in 7.5.2 version
