Hi All,
I'm trying to setup a server rendering mapnik tiles on demand using tilecache.
It seems to be working intermittently but most requests result in the following
response being returned to the browser when requesting new tiles.
An error occurred: failed mapping file: Cannot allocate memory
File "/home/tilecache/app/TileCache/Service.py", line 221, in modPythonHandler
host )
File "/home/tilecache/app/TileCache/Service.py", line 205, in dispatchRequest
return self.renderTile(tile, params.has_key('FORCE'))
File "/home/tilecache/app/TileCache/Service.py", line 138, in renderTile
data = layer.render(tile)
File "/home/tilecache/app/TileCache/Layer.py", line 411, in render
return self.renderTile(tile)
File "/home/tilecache/app/TileCache/Layers/Mapnik.py", line 38, in renderTile
mapnik.load_map(m,self.mapfile)
If I refresh the tile it eventually gets generated but sometimes takes several
tries. The apache access_log shows the request as a 500. The apache error_log
doesn't contain anything. I have the PythonDebug directive set to On.
Any ideas what is causing this?
Regards,
Brett
