Critical Description
When running my performance tests, as the first run, from a clean boot kicks off, and the number of users ramps up, I get from one to five of the following exceptions, that cause the transactions to fail:

Once these happen, it never happens again, and the run completes as normal. Subsequent runs, with the server warm don't exhibit this problem, which I would expect since it seems to be a problem with the initial proxy.
