Malloc failed.  Rsync did what it was supposed to do when
malloc fails.  The processes RSS is less important than
size.  Either your system ran out of available memory+swap
or hit a bug in malloc or some issue with sbrk or mmap.
In any case the worst claim you could make against rsync is
that it exposed an underlying problem.

I am curious what the point of limiting RSS to 16GB when the
addressspace is 8BG.
