[Geoserver-users] GeoWebCache seeding

tam_tran · February 15, 2014, 1:59am

Hi,

I have a PostGIS tiled layer that contains north-america OSM data. I tried
to seed it using GeoWebCache. Below are the seeding parameters:

Number of tasks: 4
Type of operation: Reseed
Gridset: EPSG:4326 (Dataset SRS: EPSG:3857)
Format: png8
Zoom start: 0
Zoom stop: 15
Style : polygon
BBox: -180 -91 180 91

MetaTilingFactor: 6x6
WMS Max Redening Time: 12000 (anticipate the seeding will take long)

After I entered submit, I saw this in Tomcat log:
14 Feb 13:18:49 INFO [seed.SeedTask] - GWC Seeder Thread-5 begins seeding
layer : osm:north_america_polygon
14 Feb 13:18:49 INFO [seed.SeedTask] - GWC Seeder Thread-6 begins seeding
layer : osm:north_america_polygon
14 Feb 13:18:49 INFO [seed.SeedTask] - GWC Seeder Thread-8 begins seeding
layer : osm:north_america_polygon
14 Feb 13:18:49 INFO [seed.SeedTask] - GWC Seeder Thread-7 begins seeding
layer : osm:north_america_polygon

Did not see anything showed up on the log until after about 3 hours, the
following messages showed up:

I have no ideas what went wrong and appreciate someone can tell what I did
wrong. I need to be able to seed the layer. Otherwise, the performance
will be unacceptable.

Many thanks in advance.

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:

allowed and has been forcefully stopped. Max rendering time is 12000.0s

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!).

You’ve got a value slightly larger than 90 for your North/South. Looking at your BBOX, you have:

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

Hi Jonathan,

Thanks for your response. In fact I had tried previously without entering
anything in the BBOX and got the same "too close to pole" error. That was
why I tried to enter -91 and 91 values in the BBOX in hope that it would fix
the problem. This error only happened when I chose Grid set "EPSG: 4326"
and the OSM data was imported using EPSG: 3857. I did not get the "too
close to pole" error if I chose Girdset EPSG: 900913 which is basically the
same as EPSG: 3857. Was it because GeoServer tried to re-project the data
into EPSG: 4326 and got that error because some of the north-america OSM
data is too close to pole? My question is do I have the use the Grid set
that is compatible with with OSM data SRS?

Regards,
Tam

Hi,

You might want to check the bounds that the layer is using as well since one error shows you have a latitude that is 90°10.5’S

“Caused by:
org.geotools.referencing.operation.projection.ProjectionException: Latitude
90°10.5’S is too close to a pole.”
