Sounds like you're running out of memory (and swap as well).
I'd suggest adding memory (adding more swap doesn't make it faster...)
or rsyncing smaller bits at a time if possible (if there are many
hardlinks across directory trees it may not be feasible to do parts
separately as those hardlinks will be lost, for example).
