Hi Tam,
I've had similar. For whatever reason GeoServer was unable to render one of
the tiles within the rendering time (12,000 seconds!!).
>From this line:

When this happens, the entire tiling thread that called that request then
gets cancelled and thus GeoServer doesn't even bother trying. That's what
this line means:
> Problem communicating with GeoServer
So the real question is - why is one of your tiles failing to render in
12,000 seconds (3.3hrs!).
I suspect this is the root cause:

org.geotools.referencing.operation.projection.ProjectionException: Latitude

You've got a value slightly larger than 90 for your North/South. Looking at
your BBOX, you have:
> BBox: -180 -91 180 91
Try using just 90. In fact, you shouldn't even need to declare a BBOX if
you're doing the entire planet so just leave it blank.
Cheers,
Jonathan
