Troubleshooting "search load balancer" node connectivity problems

Elastic Stack Elasticsearch
1

Hi list,

I have 2 VM "search load balancer" nodes and 4 physical master + data nodes.

The 2 search load balancer nodes get disconnected from the physical nodes
very often.
In the process of troubleshooting this I was wondering about following log
entry:

[2014-01-14 09:27:41,528][DEBUG][cluster.service ]
[xxx-xxx-logs-101] set local cluster state to version 512

When is this log generated? Is this automatically scheduled or does this
ONLY occur when the cluster topology changes (something of which I presume
shouldn't happen if all runs stable)

Thanks,

Jelle

Never mind,

Root cause was a network issue which got identified.
Setting keepalive in ES kernel params solved the problem.

Cheers,
