We have issues with our ElasticSearch cluster. Somehow, the CPU usage of the master nodes decreases over time (couple of days) and then crashes the cluster's state.
We had to restart every node one-by-one to get the cluster up-and-running. We couldn't find related issues in es-cluster.log and in the gc.log file from that day, nothing different than common 'org.elasticsearch.index.mapper.MapperParsingException: failed to parse field [finished_processing.response.Result] of type [float] in document with id 'zLJXtnMBAqpKShEiTlJF'
' issues.
Does someone know what process/issue could cause this issue? Did someone experienced it before?
