[OSM-dev] tirex timeout - could not send data to client: Broken pipe

[Petr Voldán]

Hello everyone!

We created own OSM server – unfortunately there is problem when we 
render metatiles in levels 6-10. Roughly one half of metatiles is not 
rendered due to tirex time-out. The second half and also tiles in level 
11-18 are rendered correctly. We tried increase tirex timeout parameter 
(master_rendering_timeout=60), but it didn’t help. After that we found 
out problem in postgresql log:

2011-11-28 10:56:56 CET LOG: unexpected EOF on client connection
2011-11-28 10:56:56 CET LOG: could not send data to client: Broken pipe
2011-11-28 10:56:56 CET STATEMENT: SELECT AsBinary("way") AS 
geom,"landuse","natural","waterway" from ....

Our environment:
-PostgreSQL 8.4
-PostGIS 1.5
-Mapnik 0.7.1
-Tirex 0.2.0

We use standard OSM style xml : 
http://svn.openstreetmap.org/applications/rendering/mapnik/osm.xml
DB user tirex is authenticate based on ident authentication

Does anybody know what causes this issue? Thanks for you help
