<p><font size="2" face="Times New Roman"><span style="font-size:10.0pt">Hi all,<br>
<br>
I try to launch the driving_distance function with a large network<br>
consisting of 100,000 edges. Every time I launch the query, the server<br>
closes the connection unexpectedly.<br>
<br>
Any idea why? Is there a way to get a more precise error message?<br>
I only get as message: &quot;Server closed the connection unexpectedly. This<br>
probably means the server terminated abnormally before or while<br>
processing the request&quot;<br>
<br>
<br>
thanks<br>
