However, I think I have managed to track down the root cause. The good news is that the BufferOverflowException is largely harmless. It is a side-effect of the connection being closed due to an error. My guess is that the error was a combination of vegeta sending an unexpected reset frame and Tomcat maintaining state for a very small number of streams in some circumstances. If you could retest with the latest 9.0.x that would be very helpful. The memory usage, stream state maintenance and this BufferOverflowException should all be fixed.
