You probably have deleted files which are sill opened, therefore not flushed from the filesystem. Please have a read at https://access.redhat.com/solutions/2316 .

Have you tried using lsof to find openfiles?

@bchanakya You can check something for troubleshooting :

1. check for "open" deleted files using : lsof | grep deleted

you need to clear those files - example some log files are still kept in memory after deletion by a service - so found out and clear them. use kill -9 to remove the zombies. Restart the service if that is the culprit. 

2. Use the link given by @Fran_Garcia to Truncate open files in process.

3. SOmetimes when you mount a dir on another FS which has some files - you may not be able to see those. Mount the FS somewhere else and see the unseen.
