I would be really worried about losing requests in-flight or that take a long time to run.

Is it prohibitively expensive/time consuming to get (or borrow) a bigger machine (on EC2, or in your colo, or what have you) to run MySQL on until you've figured out how to shard / scale out your application?

We are actually more than worried too, because we _know_ we're losing plenty of requests daily so trying to cut down the losses temporarily while we figure out a more long-term solution.

For the rest, this thread might give you some more info on the issue: https://news.ycombinator.com/item?id=6348903
