Hi guys,
In the company where I'm working, we have a Cluster composed of 8 nodes that are connected through a 1Gb ethernet network directly to a Switch.
On the nodes we mostly run Kubernetes, DNS Servers and some other services. The problem is that on each node, the process corosync is using from 25% to 30% of the memory constantly.
I attach the logs generated with journalctl -u corosync in one of the servers.
Some helpful information:
