@aravinth_chakravarthyr_173918 for whatever reason, the error you posted indicates that one of the SSTables for the dse_insights_local.insights_config is corrupt. As a workaround, search for thread ID CompactionExecutor:2,5 in the logs to determine which SSTable was being compacted, delete it then try to restart DSE.

Otherwise if you have a current DataStax Enterprise subscription, please log a Support ticket so one of our engineers can assist you. Cheers!
