> I am experiencing weird hangs of mapnik. Sounds like:
http://trac.mapnik.org/ticket/253 which was fixed long ago (0.6.0). So, what may be happening is you are running Mapnik from apt packages or Mapnik from source that is (accidentally) linked to the apt installed AGG pre-this fix getting pushed to the package: https://bugs.launchpad.net/ubuntu/+source/agg/+bug/344849 (thanks Andrii) So, to debug I would run: ldd /path/to/tirex.so (to see which libmapnik tirex is linked to) then: ldd /path/to/libmapnik.so (to check whether you see libagg_pic linking) Then re-install Mapnik. Since you mention below you already did this then my hunch is that you have duplicate installations of Mapnik which you need to track down. If nothing jumps out please post back the output of the 'ldd' commands above so I can pick through them. Dane > I have set up a rendering queue > mod_tile -> tirex -> mapnik 0.7.1 on debian.
