stuck after gen 1...

[fcoppey]

I have some datasets where the search get stuck for ever on gen 1 for instance.. does it happen to you too? how can I figure out what is the problem?
python is still running and using a lot of CPU... but after hours nothing happens. any idea what could be the issue?

That's pretty weird, can you share the code you are using so I can reproduce the problem?
