Disclaimer: I have a Mac in storage somewhere but it's getting on for
two decades since I last switched it on so I'm pretty unfamiliar with
the species.  I do know that the rsync on most Macs is, well, shall we
say somewhat dated?  I don't know if that has a bearing on the issue.

As you're sure it's not a memory issue then my first guess is that an
rsync process is 'defunct'.  I see this a lot when I'm developing
rsync-bpc.  Does you have the 'top' utility and do you ever see it
flagging a process as defunct?  If I'm right then I think it's likely
that you're triggering an error which is not being handled properly by
rsync-bpc, or possibly by BackupPC-XS.  In the past week or two I've
pushed fixes for a couple of issues which can cause this sort of
thing.  Can you let me know the exact versions of everything you're
using (BackupPC, BackupPC-XS, and rsync-bpc)?
