This is 1/2 GB ram, and you didn't specify the memory options of the 
xfs_repair ... so I'm going to guess at this point that you ran out of 
ram.  Paging while running xfs_repair is no fun.

How much ram do you have in this box?  Next question is, is this an ECC 
memory box?

Not sure if you are hitting a bug as much as running into something else 
like a hardware limit (RAM) or a memory stick issue.

Do you have EDAC (or mcelog) on?  Any errors from this?
