I did have firefox open while trying out chrome. I'll pay attention to any connections lost in the next 25 minutes or so.
edit: I've opened every thread I could. I thumbs up a lot of stuff. I opened like 10+ websites at the same time. Not one issue.
So I'm guessing this proves something?
Mainly that firefox (at least as you have it setup) is evil and opens up too many idle connections to the server.
Looks like firefox will even preemptively create connections before it even has something to request of the server "just in case" you click on something. That makes the vgchartz server defensive...
