I have TileCache + Mapnik working with a custom osm.xml stylesheet. When I run the tiles are served OK. But when I run TileCache under Apache (with mod_wsgi) I see incomplete tiles (with missing layers). What can go wrong? Furthermore, generating tiles is very slow. Can this have something to do with the missing layers? Thanks.

This doesn't sounds like a programming question. You should ask questions like this on instead. – Jonas Oct 27 '11 at 20:54
Probably you are right. But it might be something in constructing the stylesheet... or something. – Peter Hulsen Oct 27 '11 at 21:59
different users with different permissions perhaps? – Ragi Yaser Burhum Oct 27 '11 at 23:10
