remember that the quoted problem is spit out by the guest, not the host.

That said, the 'top' line on the frozen bhyve was:

29380 root          22  20    0  1060M   928M kqread  5 218:32 399.30% bhyve

... indicating that the bhyve had almost all it's memory... and the system
had also 500M free when I checked it.
