Hi All,

From past one month, at few instances diagnosis services failing at logstash we are getting a strange issue "exception":{"stackTrace":"ClusterBlockException[blocked by: [FORBIDDEN/4/index closed];]\n\tat org.elasticsearch.cluster.block.ClusterBlocks.indexBlockedException(ClusterBlocks.java:174)\n\tat org.elasticsearch.cluster.block.ClusterBlocks.indexBlockedRaiseException(ClusterBlocks.java:158)\n\tat

Cluster configuration: 4 data nodes, 3 master nodes and 3 client nodes  
Elasticsearch version:ES: 2.3.1  
Everytime we perform rolling restart and the problem goes away. Is there a specific reason this problem is occurring?

Something is closing indices in your cluster - [https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-open-close.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-open-close.html)

What sort of access control do you have in place?

Hi,  
There is no such access control mechanism as of now.
