SPECweb96 Issue: Class3 between 0.009 and 0.011

What is this "mix for class Class3 is 0.012, must be between 0.009 and 0.011"?

What that means is that your run just missed making the correct mix for Class 3 (which is the hardest class to hit right). The problem is that at low load levels the mix is such that there are not that many operations for Class 3 (Class 3 is defined to be only 1% of all requests -- at least between 0.009 and 0.011), thus it is possible to get bit by an unfortunate sequence from the random number generator.

If this happens for one of the data points near the peak, the run is considered "invalid"; if this happens (as it often does) during one of the very low data points it may be ignored.

If this does not stablize at higher performance levels (where there are enough Class3 requests to even out the random generation), then you might have a problem to investigate...
