How many files are involved? If the number is very high, the memory
usage of rsync will cause the machine to run out of memory. 40GB of mail
would suggest a lot of little files...
In that case, see if it's possible to run rsync on subdirectories of
the tree (hardlinks outside such a subdir is a showstopper for that
approach, assuming you're using -H).
