Recently we found one issue: our es cluster had three nodes which storage our product env log, one node of cluster bulk queue size always close to full, other nodes not.
i adjust our send client config file, remove the node and watch it. during some times, i found the node bulk queue size still close to full size.
Who can help solve this problem？
