Thanks for your response. None of the processes are deleting any index files. One data directory is only pointed by one core.
We are writing data at a high ingestion rate (100,000 records per second). Commit happens once every 30 seconds. Also a periodic service runs to backup the data to our backup data store. This service starts by saving commit point & when its done, it released the commit point. Could this combination of these factors some how cause the deletion of files? -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
