Issue

• /usr/bin/find directories with .snapshot return exit code 1 (echo $? = 1) on RHEL 6.4 servers. the same command on RHEL 5.x works fine.
• Example of warning message from both 6.4 and 5.x servers:

find: File system loop detected; `/gfs/amm/data_log/.snapshot' is part of the same file system loop as `/gfs/amm/data_log'.

OR

 $ mkdir -p a/b
> $ sudo mount --bind a a/b
> $ find a; echo $?
> a
> find: File system loop detected; ‘a/b’ is part of the same file system loop as ‘a’.
