As a follow up...<br><br>I still don't know the reason for the crash, but I've finally got a large enough ubuntu system installed and loaded up with PostGIS, pgrouting 1.5, etc. It appears to be working okay, although psycopg2 is returning "no result" in a different manner - that threw my Python code a little.<br>
<br>So whatever the bug was, it appears to have been fixed in pgRouting 1.5.<br><br>Whilst waiting for the disk to arrive, I did run a series of scripts to remove links less than a fixed distance (1m I think it was) and links with the same start and end node. This did not fix the problem.<br>
The scripts also cleaned up the length & cost information, so I shall be running them again this evening. With the whole planet.osm dataset loaded, they took a while to run & re-index...<br><br><br>Richard (M)<br>
