Often we are seeing "Connection reset by Peer" after migrating to ES 6.8. We are still using ES 6.1.4 client. It recovers, but often there is Connection reset by Peer. Any solution or how can this be debugged. ---

I would recommend upgrading to the 6.8 client and see if this makes a difference. You should always use the same version of the client as the server. There are quite a lot of changes that have gone in between 6.1 and 6.8 which could cause problems. ---

Ok, planning on upgrading to the 6.8 client. However, what other reasons could cause this issue ---

We are sseeing this because of the idle connection timeout. But in this case, i thougth the REstClient is supposed to retry all other nodes. WHy i dont see that happening. ---
