Summary0000367: Neato runs forever on a certain example
Description



As described in the FAQ; a bugreport for a "neato that runs forever".
The following (small) graph keeps neato running:
<CD>
commandline: neato <inputfile>
</CD>
Steps To Reproduce

graph System {
        margin=".2, .4";
        overlap=false;
        spline=true;
        size="7.8, 11";
        fontsize="8";
node [shape=box, fixedsize=true, width=.375, height=.375];

edge [spline=true, weight=2.0];
}
Additional Information

I use neato in a webapplication that renders topologies.
Some topologies cause neato to run forever which causes a failure in my app (app kills neato on timeout).
The content of the graph is dynamic and varies over time.
Above an example of a graph that runs forever.

nodename explanation:
Dxxxx equals Device xxxx
Nxxxx equals Network xxxx
Dxxxx--Nxxxx link between device and network
