Hello Adil,
Thank you for your inquiry. I have CC’d the pgRouting list on this response because others might have the same questions.
I think we probably need to know more about your installation like:
What platform / OS are your running?
What version of Postgresql? select version();
What version of PostGIS? select postgis_full_version();
What version of pgRouting? 1.01, 1.02, 1.03?
What data do you have loaded?
What is your sql query?
So in the example that you try on my site, the server did not crash, but did not find a result either. This is most likely a data problem and in fact we are aware that nodes at border crossings are not match so the network breaks when you try to cross between countries.
In general the server should never crash, but there are some bugs where this is unfortunately the case. If you can simplify the problem to a smallish data set and a query that causes a crash, I’m sure the developers will make some priority to fix this issue.
If you are just not getting a result versus get a real server crash, then it is likely a data problem. OK, so how do you know which is which? Use pgAdmin3 and open the SQL window, and enter you SQL query. It will report if the server crashed or it will return with no records if it can not find a route between your start and end points.
Also you need to be aware that bounding box for segments between the start and end point on a horizontal or vertical lines need to be expanded more to make sure you load enough segments to get a solution.
Hope this helps,
-Steve

but i see that pgrouting crash when calculating a long distance. I have a similar problem.
Is this normal?
