Hi,

What does ES do after starting and after the information "recovered [639]  
indices into cluster\_state" in log file? It is using 100% of processor for  
about 10 minutes in my case.

Thanks for the answer.

Best regards.

Hello!

After the restart, ElasticSearch starts the recovery process, which loads the cluster state from your gateway. This can be quite resource intensive for both CPU and I/O.
