This looks like a standard 'edge of the earth' issue. Your data has
been clipped so that these artifacts don't appear in EPSG:4326 (look
around Egvekinot). The problem here is that when a polygon, such as
Africa, extends beyond the edge of the map the points are being
projected to the other side of the view. The results are the horizontal
lines as the polygon races across the map. You will likely need to do
data preparation to split some continents across your edge of the world.

Good afternoon
I need to display some maps which are centered on the Pacific Ocean. After
having spend some times, looking at the different SRS available in
GeoServer, i run a bunch of test with the EPSG=3349.
This is the type of map, i obtain:
http://www.fao.org/figis/geoserver/wms?bbox=-22041257.773878,-14322638.1338445,22041257.773878,13613811.2422463styles=Format=application/openlayersrequest=GetMapversion=1.1.1layers=fifao:UN_CONTINENTwidth=800height=362srs=EPSG:3349
It is effectively centered on the Pacific ocean but, many polygons are not
correctly displayed.
Normal view with EPSG:4326:
http://www.fao.org/figis/geoserver/wms?bbox=-198.0,-98.681184,198.0,92.3047800085styles=Format=application/openlayersrequest=GetMapversion=1.1.1layers=fifao:UN_CONTINENTwidth=800height=362srs=EPSG:4326
Is it a bug of GeoServer or did I make some mistakes defining the parameters
of my map?Is it the correct SRS with the right bounding box?
My data is extracted from an Oracle DB and i am using GeoServer 1.6.5. I
tried with the 1.7.0-RC1-pre version, it have obtained a white page.
Thanks for helping me.
