[Geoserver-users] Can't Compute Bounds for Tile Layer Warnings

Hi,

I get many of following kind warnings on GeoServer 2.3.3 log file.

WARN [gwc.layer] - Can’t compute bounds for tile layer workspace:layer in CRS EPSG:900913. Assuming full GridSet bounds. (null)
WARN [gwc.layer] - Can’t compute bounds for tile layer workspace:layer in CRS EPSG:4326. Assuming full GridSet bounds. (null)

What do they mean and why they happen? I can see the Native Bounding Box and Lat/Lon Bounding Box of each layer on Edit Layer screen.

Best regards,
