mongoDB error : aborting after fassert() failure

What to do when facing errors on mongoDB “aborting after fassert() failure” I like errors, in mongoDB this is the first error I faced and luckily many times. This error i faced during restoring name-space on local and restarting db system. I am still searching the exact root cause of this issue but i am able to resolve the current problem through below steps. Remove all relevant namespace files from data-file route path.. Now repair mongo instance using mongod process. mongod --repair ////////// execute command from bin folder path  Then start server using mongd process, if started server successfully then .. mongod  ////////// execute command from bin folder path Restore last backups as normal process. Now check database by connecting mongo shell. Thanks for reading,  Please comment your experience if you faced and also share knowledge if you have better steps to resolve... https://www.facebook.com/pages/Sql-DBAcoin/523110684456757
