Briefly, this error occurs when Elasticsearch tries to reload a file, possibly a configuration or data file, and encounters an issue. This could be due to file corruption, incorrect file permissions, or the file being in use by another process. To resolve this, you could try closing other processes that might be using the file, checking the file’s permissions and ensuring Elasticsearch has the necessary access, or restoring the file from a backup if it’s corrupted.
