Hi,
I'll implement a automatic statistic on this so that I'll get notified when this happens. It should not happen, unless you are unlucky and search when I am uploading an updated on the server code and it breaks the search for a a second of too, but I doubt it. It could be that on of sub searches returns a result that I don't treat properly.
so the next version of the Ecosystem will allow me to watch this automatically. Thanks for reporting.
Bye,
Jean
