Hi all, I got a production Elasticsearch cluster running on Azure. On 9th Nov, Azure agent started a yum update on OpenSSL and Python libraries. This action crashes one of the index. Have anyone with Elasticsearch on Azure experience this before ? I would like to know if Elasticsearch is indexing data and the following libraries has been updated, Will it crash Elasticsearch ?
