Hello. We have serious issues with ES 2.1. and Marvel. Cluster is becoming Yellow and all the writes operations were blocked ! In state, it's not normal. Everything came back to normal when we removed Marvel plugin. Here is the log: [https://gist.github.com/anonymous/930ff95e9172358fe81c](https://gist.github.com/anonymous/930ff95e9172358fe81c) ---

Hi, The log indicates that a node left and so marvel failed to retrieve statistics for the shards (series\_556[2]) that was located on this node. It makes sense and I don't think that this is not what blocked the writes operations. Can you check if you have other error messages in your logs? Can also you give us the output of `GET /_cat/shards?v` ? Thanks ---
