The "Pink Tile Syndrome" has been reported by a variety of users,
usually on data which is not pre-cached. I haven't personally run into
the problem much, but we've recently (2.3/SVN) added functionality to
help reload tiles which suffer pink tile syndrome.

To enable this functionality in OpenLayers 2.3, simply set the variable:

OpenLayers.IMAGE_RELOAD_ATTEMPTS = 2;

or something similar.
