Do you mean that the statement hadn't been fully transmitted yet?
If so, the backend would have just been waiting for the rest of the

You seem to have a lot of variables there --- maybe you should do some
experimenting to narrow down what the problem is. I'd expect all of
those things to take some time, but not more than a few seconds...
