Hi Hugh, Thanks for your reply. Now that we have some more constants, we can focus on our side of things and stop trying to second guess Virtuoso.
We realized that something might be wrong with our data ( see snip below ). Now, how did this happen? I have no idea. But we will soon ;) I have noticed that we usually run into obscure bugs ( source is far away from symptoms ) when someone doesn't change the "port" setting soon enough during their install lifecycle ( remove the implicit :80... I can't remember where that setting is located at this point ). Not sure if these are related, but I have a feeling they might be. Thanks!
