What's happening is VA is setting up for millions of responses at that point. It has to set up command segments, the speech engine and all that good stuff, so, yeah, depending on your system, it could take a little bit of time and/or crash out. I don't know what it would take to crash an individual system, so there is no cap on what's allowed. I'm going to look at catching that exception at that point and see if it can be handled (my guess is no, but it's worth a try).
