Nope - this is not an error at all in fact, just verbose debug output
from the xc_save process. 

The real error is:

Basically this means that you didn't have enough memory to do the 
migrate (during a migrate of a domain of size xMB, you temporarily 
need to have a spare x+8 MB free.) 

The error handling / error message could certainly usefully be
improved :-) 



cheers,
