I updated the coastline shapefiles used by the mapnik layer last night. The previous update was about 4 weeks ago. If no one edits any data in an area after the coastline shapefiles are changed then it may be a long time before the tiles are rendered again to pick up the changes (as you are seeing here). Normally I force the zoom 0 - 12 tiles to re-render across the world each time I update the coastline shapefiles but it takes too long to do all zoom levels on each update. Back in January I ran a process to re-rendered all tiles last rendered prior to 1st Oct 2010 across the full 0-18 zoom range. This took a few weeks to complete and should have picked you older changes. I will consider running it again with a more recent cut-off point. Perhaps some of the other discrepancies are due to newer edits to the coastlines?
