Thanks for filing @shacharSirotkin, is that the full stack trace from the panic? It would be helpful to have more specific information about where the panic occurred in buildVMMetrics.

@shacharSirotkin Hey! I'd love to take a look at this, if you could please supply the full stack trace from the panic you see.
