Here is the meta data I use and it works fine.

        "opacity" "50"
        "redraw_interval" "600"
        "tile_source" "redraw"
        "refresh_interval" "300"

Thanks Luper,

Actually I did see your fix and tried it yesterday. No help... sorry. 
The only fix I have
so far is to put a script in the background to wipe the cache. Because 
there are dynamic
layers and static layers in the same map file I thought that might cause 
a problem. I tested
with both nocache and redraw with one single dynamic layer and had the 
same issues. I
am wondering if this is shape file related, or timestamp related as I 
don't see anyone else
having issues.
