If your GWCtilecache is defined in EPSG:4326 and your OpenLayers map option is set to anything other thatn EPSG.4326 then there is going to be a discrepency between resolutions. This will result in pink tiles.
Hope this helps,

I am working on a simple map site (5 layers) at http://unesco1.nomadlife.org/ and I am having performance problem that I am trying to figure out. The site is running on a GoDaddy VPS with 4GB of RAM .
I set up caching for my base map (which is a Geotiff image) and it works well /geoserver/gwc/demo/UNESCO:BaseMap?gridSet=EPSG:4326&format=image/jpeg
Now the cache runs on ESPG:4326 while my OpenLayer code runs on yx : "ESPG:4038"
Does this make any difference weather my WMS call hits the cache or not? Is there anyway to verify whether the cached tileset is being used by the OpenLayer call?
