After removing the Xorg log file still the space still shows as consumed for the given filesystem on my RHEL server.

Issue

• After taking the backup and removing the Xorg log file still the space getting increase.
• Root FS is getting full because of the Xorg files. Even though I have taken a backup and deleted them, the files are still occupying the space on the root FS.

    [root@server]# cat lsof | grep deleted
    Xorg       3009        0    0w      REG              253,0  18758591232     264962 /var/log/Xorg.0.log.05122015old (deleted)
