Oddity: rsync *should* be recursing, and dealing with very large number of

tried adding -r, and changing --delete to --delete-delay, and no joy.
All boxes are current, or fairly current, CentOS 7.
The only thing I know of that's likely to cause rsync to run out of memory
is when there are a huge number of hard links and you are using the "-H"
option to preserve them. (If you think you don't have many, look under
/var/lib/yum/yumdb and /usr/share/zoneinfo.)
And FYI, rsync doesn't do a very good job of preserving hard links when
going to a destination that already has some of the files. It doesn't
break any existing hard links at the destination, so you can end up with
a hard link topology that is somewhat different from the source. I have
to run some very messy audits to make sure all copies of my backups have
the same arrangement of hard-linked files.
