Solution :
Delete the associated process ID and restart the service if required....that should fix the problem.ls -ld /proc/*/fd/* 2>&1 | fgrep '(deleted)'
If you want to check the specific partition you can grep the value say like, if you need to check /var do
NOTE :ls -ld /proc/*/fd/* 2>&1 | fgrep '(deleted)' | grep var
MOSTLY it will be the below one thats causing the problem
