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:
14 Feb 16:34:06 ERROR [geoserver.ows] -

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.
Regards,
Tam
