Hi,

Done:

atom:/d1/motion/cam1# /root/getdents  > /tmp/cam1-out.txt
atom:/d1/motion/cam1# cd ../cam2
atom:/d1/motion/cam2# /root/getdents  > /tmp/cam2-out.txt
atom:/d1/motion/cam2# cd ../cam3
atom:/d1/motion/cam3# /root/getdents  > /tmp/cam3-out.txt

Currently I do not see any dupes, however I have a script that moves 
images out of the directory once an hour:
0 * * * * /usr/local/bin/move_to_old2.sh > /dev/null 2>&1

I'll disable that for now and see if this recurs, if it does, I'll gather 
additional output and send it out, thanks.

Justin.
