I think we've talked about this before on the mailing list? This is most
likely an OpenLayers bug, if it's the same thing I've run into: have you
been able to reproduce it without OpenLayers in the loop?
Basically, I don't trust OpenLayers WMS to always request tiles on grids
after looking at TileCache in OpenLayers for a while. Figuring out why
is high on my priority list for OpenLayers development, but at the
moment, OpenLayers development is not high on my priority list.
It's unfortunate that this is happening, but I haven't been able to come
up with a reasonable test case that can reproduce it, which makes
debugging or fixing it hard.
