Indexed records are getting deleted in Solr 7.7.2 version. This is happening only in 1 instance. There is no specific pattern when it is getting deleted. In 18000 records, sometimes around 2000 or 8000 are remaining after deletion. Physical memory is 95% used. No out of memory error. No programmatical scheduler or activity is happening during this deletion. Please suggest
I tried re-indexing multiple times, but again getting deleted at unknown time. Sometimes it is 1 day, sometimes it is 3 days or more and no specific pattern. Tried checking logs, nothing found suspicious (no memory error)
