For me both gdalinfo reports look the same except the coordinates. Pity.
That tiff works with the WMS request does not guarantee that it returns with
the GetMap that is sent by GWC. Because of that it would be good to capture
just the failing request with all the parameters and especially BBOX. Perhaps
WMS or JAI does not like to draw some adjacent granules together. That was why
I asked to send the gdalinfo reports but they did not reveal anything.
I do not understand much about the error message but perhaps the real error
happens somewhere here
Caused by: java.lang.RuntimeException: - Unable to render RenderedOp for this
operation.

You can do a desperate trial by re-writing the failing image with GDAL
gdal_translate -of GTIFF -co tiled=yes -co compress=LZW failing.tif
new_copy.tif and change the new image into the mosaic directory.

GDALinfo output below. As I say, though, the TIFF which will not cache will
be returned when requested by WMS.
