Just curious, why so many problems with VMs?

I would think most applications need real time clocks that provide consistent valid data?


you might try a larger AWS instance to make sure your are getting 100% of the box; might help some.

can you reproduce the same issue on real hardware?  We’ve seen all kinds of weird timing issues that could account for this running on aws.
