curious root find running

[brad clawsie]

hi

while sitting at my computer tonight i noticed a great deal of disk
activity. i found that this process was running:

$ ps -auxwww 1463
USER   PID %CPU %MEM   VSZ   RSS  TT  STAT STARTED      TIME COMMAND
root  1463  4.3  0.1  1876  1404  ??  D     3:01AM   0:07.26 find /usr
-xdev -type f ( -perm -u+x -or -perm -g+x -or -perm -o+x ) ( -perm
-u+s -or -perm -g+s ) -print0

any idea why this is running? is it part of a sanctioned background
process?

thanks!
brad
