Please give the attached patch a try - afaict it should eliminate
the host crash, but I'm pretty certain you'll then see the guest
misbehave. Depending on what other load you place on the
system as a whole, you're either overloading it (i.e. we're
running out of mapping space in the hypervisor) or there's a
mapping leak that - so far at least - I can't spot.

In any event I'd suggest you try running a debug build of the
hypervisor, so that eventual problems can be spotted earlier.
