I am using elasticsearch cluster of 8 node (3Master+3data+2coordinate).In data node there is a file called **java\_pid4907.hprof** of 7.2 gb in elasticsearch data directory this file is present in all elasticsearch data node.Is this file is generated by elasticsearch or OS ? Is it safe to delete this file? ![test](https://us1.discourse-cdn.com/elastic/original/3X/5/1/511604dc26a1c56d41a9f7adf4fe668370ca17f1.png) ---

The file name indicates it's a heap dump, probably auto-generated by Elasticsearch on an out-of-memory error. Elasticsearch has no further need for this file. ---
