image files with upper case file name do not exist

[ZD Yu]

I ran into the exact same problem as described in an earlier thread:

http://mail-archives.apache.org/mod_mbox/incubator-olio-user/200905.mbox/%3c4a208815.7050...@sun.com%3e

The client reported a lot of errors like: (note the image file name with
upper case E and T)
       Image at http://sut/fileService.php?cache=false&file=E1886T.jpg size
of 0 bytes is too small. Image may not exist

But running "select imagethumburl from SOCIALEVENT" on Olio database did not
return any image file name with upper case.

In the above email thread, Akara said:

       Unless the file system has an issue with case sensitivity, it
seems your DB is out of sync.


My question is: what kind of mis-configuration may cause DB out of sync?

Thanks, ZD
