Please ignore... it looks like the user was creating sparse files.

Good Morning,

   We just came across an interesting issue... three files were created last night that ls reports as having a size in the exabytes (though du shows as being the proper size).

-rw-r--r-- 1 <user / group>  611932097548345030 Apr 21 15:34 file3

 du -h file1
878K    file1
 du -h file2
878K    file2
 du -h file3
582K    file3

We are running 2.5.3 on CentOS 6.5
