dijkstra (#16) - RAM Usage (#233) - Message List

Hi!

I installed pgRouting with the packages from  http://www.kyngchaos.com/software:postgres on OSX. I set up a table with 2260 edges and applied the Dijkstra as well as the A* algorithm:

SELECT * FROM

shortest_path_astar( 'SELECT

oid AS id, anfang::int4 as source, ende::int4 as target, hinweg::double precision as cost, x1,y1,x2,y2

FROM kanten',266701249,30736715,false,false);

I seems to be impossible to solve on my 2 GB RAM machine. VM jumps up to >21GB of RAM usage, causing the computer to totally break down. After more than 12 hours I killed the postgres process...

I don't consider a network with 2260 edges as large. How can I limit the memory usage of the search function?
