OK, so lets just assume some part of memory (or CPU state, or memory
loaded off disk...)

You said before that it was happening on a 32GB image - is it *only*
happening on a 32GB or bigger VM, or is it just more likely?

I think you also said you were using 1.7; have you tried an older
version - i.e. is this a regression in 1.7 or don't we know?
