Briefly, this error occurs when Elasticsearch tries to execute a callback function before closing an index, but fails due to issues like insufficient resources, network problems, or bugs in the code. To resolve this, you can try increasing system resources, checking network connectivity, or debugging the callback function to identify and fix any coding issues. Additionally, ensure that your Elasticsearch version is up-to-date as this could be a bug that has been fixed in a newer version.
