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 ....
Do you have messages like "sending HUP to worker 'mapnik' with pid xxx (due to timeout)" in your /var/log/daemon.log? If yes, then the mapnik backend has timed out, probably because you forgot to set backend_manager_alive_timeout to a similarly high value (55 would be good in your case).
Also, try and make sure that when you pre-render stuff on critical zoom levels, you only have one rendering thread (i.e. enqueue your requests with a suitable priority like 99).
